+.SH DESCRIPTION
+.PP
+.B dmake
+is a re-implementation of the UNIX Make utility with significant enhancements.
+.B dmake
+executes commands found in an external file called a
+.I makefile
+to update one or more target names.
+Each target may depend on zero or more prerequisite targets.
+If any of the target's prerequisites is newer than the target or if the target
+itself does not exist, then
+.B dmake
+will attempt to make the target.
+.PP
+If no
+.B \-f
+command line option is present then
+.B dmake
+searches for an existing
+.I makefile
+from the list of prerequisites specified for the special target \fI.MAKEFILES\fR
+(see the STARTUP section for more details).
+If "\-" is the name of the file specified to the
+.B \-f
+flag then \fBdmake\fR uses standard input as the source of the makefile text.
+.PP
+Any macro definitions (arguments with embedded "="
+signs) that appear on the command line are processed first
+and supercede definitions for macros of the same name found
+within the makefile.  In general it is impossible for definitions found
+inside the makefile to redefine a macro defined on the command line, see the
+MACROS section for exceptions.
+.PP
+If no
+.I target
+names are specified on the command line, then \fBdmake\fR uses the first
+non-special target found in the makefile as the default target.
+See the
+.B "SPECIAL TARGETS"
+section for the list of special targets and their function.
+Makefiles written for most previous
+versions of
+.I Make
+will be handled correctly by 
+.B dmake.
+Known differences between \fBdmake\fR and other versions of make
+are discussed in the
+.B COMPATIBILITY
+section found at the end of this document.
+.B dmake
+returns 0 if no errors were detected and a non-zero result if an error
+occurred.
+.SH OPTIONS
+.IP "\fB\-A\fR"
+Enable AUGMAKE special inference rule transformations
+(see the "PERCENT(%) RULES" and "AUGMAKE META RULES" sections), these are
+set to off by default.
+.IP "\fB\-B\fR"
+Enable the use of spaces instead of <tabs> to begin recipe lines.
+This flag equivalent to the .NOTABS special macro and is further described
+below.
+.IP "\fB\-c\fR"
+Use non-standard comment stripping.  If you specify \fB\-c\fP then
+.B dmake
+will treat any \fB#\fP character as a start of comment character wherever it
+may appear unless it is escaped by a \e.
+.IP "\fB\-C [+]file\fR"
+This option writes to \fIfile\fP a copy of standard output and
+standard error from any child processes and from the
+.B dmake
+process itself.  If you specify a \fB+\fP prior to the file name then
+the text is appended to the previous contents of \fIfile\fP.
+This option is active in the MSDOS implementation only and is ignored
+by non-MSDOS versions of
+.B dmake.
+.IP "\fB\-d\fR"
+Disable the use of the directory cache.  Normally \fBdmake\fP caches directories
+as it checks file timestamps.  Giving this flag is equivalent to the
+\&.DIRCACHE attribute or macro being set to \fIno\fP.
+.IP "\fB\-E\fR"
+Read the environment and define all strings of the
+form '\fBENV\-VAR\fP=\fIevalue\fP'
+defined within as macros whose name is \fBENV\-VAR\fP,
+and whose value is '\fIevalue\fP'.
+The environment is processed prior to processing the user
+specified makefile thereby allowing definitions in the makefile to override
+definitions in the environment.
+.IP "\fB\-e\fR"
+Same as \-E, except that the environment is processed after the
+user specified makefile has been processed
+(thus definitions in the environment override definitions in the makefile).
+The \-e and \-E options are mutually exclusive.
+If both are given the latter takes effect.
+.IP "\fB\-f file\fR"
+Use \fBfile\fR as the source for the makefile text.
+Only one \fB\-f\fR option is allowed.
+.IP "\fB\-g\fR"
+Globally disable group recipe parsing, equivalent to the .IGNOREGROUP
+attribute or macro being set to \fIyes\fP at the start of the makefile.
+.IP "\fB\-h\fR"
+Print the command summary for \fBdmake\fR.
+.IP "\fB\-i\fR"
+Tells \fBdmake\fR to ignore errors, and continue making other targets.
+This is equivalent to the .IGNORE attribute or macro.
+.IP "\fB\-K file\fR"
+Turns on \fB.KEEP_STATE\fP state tracking and tells \fBdmake\fP to use
+\fIfile\fP as the state file.
+.IP "\fB\-k\fR"
+Causes \fBdmake\fR to ignore errors caused by command execution and to make
+all targets not depending on targets that could not be made. 
+Ordinarily \fBdmake\fR stops after a command returns a non-zero status,
+specifying \fB\-k\fR causes \fBdmake\fR to ignore the error
+and continue to make as much as possible.
+.IP "\fB\-m[trae]\fR"
+Measure timing information. Print the time when targets and/or recipes
+are started and finished to stdout. The following format is used:
+.IP ""
+\fB{s|e} {target|recipe} time maketarget\fP
+.IP ""
+\fBs\fP or \fBe\fP stands for started or ended, \fBtarget\fP or
+\fBrecipe\fP denotes if this line refers to the whole target or a
+recipe. \fBtime\fP is displayed in Unix time format, i.e. the number
+of seconds since an epoch.  (Since 1970-01-01T00:00:00Z).  \fBmaketarget\fP
+obviously represents the target the timing information is given for.
+The optional flags \fB[trae]\fP can be used to change the information that
+is displayed.  If no optional flags are given only the \fBt\fP flag
+is assumed to be selected, ie. \fB\-mt\fP.  The optional flags stand for:
+.RS
+.IP "\fBt\fP"
+Display the start and end time of each target.
+.IP "\fBr\fP"
+Display the start and end time of each recipe.
+.IP "\fBa\fP"
+Display the target as an absolute path, i.e. prepend the current working
+directory.
+.IP "\fBe\fP"
+Also display the start and end time of the \fB$(shell command)\fP function
+(aka. shell escape) macros.
+.RE
+.IP "\fB\-n\fR"
+Causes \fBdmake\fR to print out what it would have executed,
+but does not actually execute the commands.  A special check is made for
+the string "$(MAKE)" inside a recipe line, if it is found,
+the line is expanded and invoked, thereby enabling recursive makes to give a
+full description of all that they will do.
+This check is disabled inside group recipes.
+.IP "\fB\-p\fR"
+Print out a version of the digested makefile in human readable form.
+(useful for debugging, but cannot be re-read by \fBdmake\fP)
+.IP "\fB\-P#\fR"
+On systems that support multi-processing cause \fBdmake\fP to use \fI#\fP
+concurrent child processes to make targets.
+See the "MULTI PROCESSING" section for more information.
+.IP "\fB\-q\fR"
+Check and see if the target is up to date.  Exits with code 0 if up to date,
+1 otherwise.
+.IP "\fB\-r\fR"
+Tells \fBdmake\fR not to read the initial startup makefile, see STARTUP
+section for more details.
+.IP "\fB\-s\fR"
+Tells \fBdmake\fR to do all its work silently and not echo the commands it is
+executing to stdout (also suppresses warnings).
+This  is equivalent to the .SILENT attribute or macro.
+.IP "\fB\-S\fR"
+Force sequential execution of recipes on architectures which support
+concurrent makes.  For backward compatibility with old makefiles that have
+nasty side-effect prerequisite dependencies. (Implies -P1)
+.IP "\fB\-t\fR"
+Causes \fBdmake\fR to touch the targets and bring them up to date
+without executing any commands.
+Note that targets will not be created if they do not already exist.
+.IP "\fB\-T\fR"
+Tells \fBdmake\fP to not perform transitive closure on the inference graph.
+.IP "\fB\-u\fR"
+Force an unconditional update.  (ie. do everything that would
+be done if everything that a target depended on was out of date)
+.IP "\fB\-v[cdfimrtw]\fR"
+Verbose flag, when making targets print to stdout what we are going to make
+and what we think its time stamp is.  The optional flags \fB[cdfimrtw]\fP can be
+used to restrict the information that is displayed.  In the absence of any
+optional flags all are assumed to be given (ie. \fB\-v\fP is equivalent to
+\fB\-vcdfimrtw\fP).  The meanings of the optional flags are:
+.RS
+.IP "\fBc\fP"
+Notify of directory cache operations only.
+.IP "\fBd\fP"
+Notify of change directory operations only.
+.IP "\fBf\fP"
+Notify of file I/O operations only.
+.IP "\fBi\fP"
+Notify of inference algorithm operation only.
+.IP "\fBm\fP"
+Notify of target update operations only.
+.IP "\fBr\fP"
+Force output of recipe lines, warnings and executed commands. This switch
+is usefull when debugging makefiles that disable the output using the @
+or @@ property for recipe lines or the .SILENT target/attribute.
+It also overrides the -s flag.
+.IP "\fBt\fP"
+Keep any temporary files created; normally they are automatically deleted.
+.IP "\fBw\fP"
+Notify of non-essential warnings (these are historical).
+.RE
+.IP "\fB\-V\fR"
+Print the version of \fBdmake\fR, and values of builtin macros.
+.IP "\fB\-W target\fR"
+Run \fBdmake\fP pretending that \fItarget\fP is out of date.
+.IP "\fB\-w target\fR"
+\fIWhat if?\fP Show what would be made if \fItarget\fP were out of date.
+.IP "\fB\-x\fR"
+Upon processing the user makefile export all non-internally defined macros
+to the user's environment.  This option together with the \-e option
+allows SYSV AUGMAKE recursive makes to function as expected.
+.IP "\fB\-X\fR"
+Inhibit the execution of \fB#!\fP lines found at the beginning of a makefile.
+The use of this flag prevents non-termination of recursive make invocations.

+.SH STARTUP
+When
+.B dmake
+begins execution it first processes the command line and then processes
+an initial startup-makefile.
+This is followed by an attempt to locate and process a user supplied makefile.
+The startup file defines the default values of all required control macros
+and the set of default rules for making targets and inferences.
+When searching for the startup makefile,
+.B dmake
+searches the following locations, in the order specified,
+until a startup file is located:
+.LP
+.RS
+.IP 1.
+The location given as the value of the macro
+MAKESTARTUP defined on the command line.
+.IP 2.
+The location given as the value of the environment variable MAKESTARTUP
+defined in the current environment.
+.IP 3.
+The location given as the value of the macro
+MAKESTARTUP defined internally within \fBdmake\fP.  In this version, the
+internal definition of MAKESTARTUP is "$(DMAKEROOT)/startup.mk", so you
+can set the environment variable DMAKEROOT to the location of your startup
+directory.
+.sp
+If DMAKEROOT is not changed, for native Windows dmake versions its value
+defaults to "$(ABSMAKECMD:d)startup" (see definition of ABSMAKECMD for
+details).
+For unix like versions build with the autotools build system it defaults
+to the value of "${prefix}/share/startup" at build time. The actual value,
+usually something like /usr/local/share/startup can be checked with the \-V
+command line switch.
+.RE
+.LP
+The above search is disabled by specifying the \-r option on the command line.
+An error is issued if a startup makefile cannot be found and the \-r
+option was not specified.
+A user may substitute a custom startup file by defining
+the MAKESTARTUP environment variable or by redefining the
+MAKESTARTUP macro on the command line.
+To determine where
+.B dmake
+looks for the default startup file, check your environment or issue the command
+\fI"dmake \-V"\fP.
+.PP
+A similar search is performed to locate a default user makefile when no
+\fB\-f\fP command line option is specified.
+By default, the prerequisite list of the special target .MAKEFILES
+specifies the names of possible makefiles and the search order that
+\fBdmake\fP should use to determine if one exists.
+A typical definition for this target is:
+.RS
+.sp
+\&.MAKEFILES : makefile.mk Makefile makefile
+.sp
+.RE
+\fBdmake\fP will first look for makefile.mk and then the others.
+If a prerequisite
+cannot be found \fBdmake\fP will try to make it before going on to the next
+prerequisite.  For example, makefile.mk can be checked out of an RCS file
+if the proper rules for doing so are defined in the startup file.
+.PP
+If the first line of the user makefile is of the form:
+.RS
+.sp
+#!command command_args
+.sp
+.RE
+then \fBdmake\fP will expand and run the command prior to reading any
+additional input.  If the return code of the command is zero then \fBdmake\fP
+will continue on to process the remainder of the user makefile, if the return
+code is non-zero then dmake will exit.
+.PP
+\fBdmake\fP builds the internal dependency graph as it parses a user specified
+makefile.  The graph is rooted at the special target \fB.ROOT\fP. .ROOT is the
+top level target that dmake builds when it starts to build targets.  All user
+specified targets (those from the command line or taken as defaults from
+the makefile) are made prerequisites of the special target \fB.TARGETS\fP.
+\fBdmake\fP by default creates the relationship that .ROOT depends on .TARGETS
+and as a result everything is made.  This approach allows the user to customize, within
+their makefile, the order and which, target, is built first.  For example the
+default makefiles come with settings for .ROOT that specify:
+.sp
+.RS
+\&.ROOT .PHONY .NOSTATE .SEQUENTIAL : .INIT .TARGETS .DONE
+.RE
+.sp
+with .INIT and .DONE defined as:
+.sp
+.RS
+\&.INIT .DONE .PHONY:;
+.RE
+.sp
+which nicely emulates the behaviour of Sun's make extensions.  The building of
+\&.ROOT's prerequisites is always forced to be sequential.  However, this
+definition is trivially changed by supplying the definition:
+.sp
+.RS
+\&.ROOT : .TARGETS
+.RE
+.sp
+which skips the preamble and postamble phases of building .TARGETS.
+.PP
+.B Please note
+that even though .INIT and .DONE are special exceptions, see section SPECIAL
+TARGETS, the use of self defined targets starting with `.' should be avoided
+as they would be handled as .<suffix> meta targets. The target names _INIT
+and _DONE for example would work equally well without the .<suffix>
+drawback.
+.SH SYNTAX
+This section is a summary of the syntax of makefile statements.
+The description is given in a style similar to BNF, where { } enclose
+items that may appear zero or more times, and [ ] enclose items that
+are optional.  Alternative productions for a left hand side are indicated
+by '\(->', and newlines are significant.  All symbols in \fBbold\fP type
+are text or names representing text supplied by the user.

+Where, \fBTAB\fP represents a <tab> character, \fBSTRING\fP represents an
+arbitrary sequence of characters, and
+\fBLINE\fP represents a
+possibly empty sequence of characters terminated by a non-escaped 
+(not immediately preceded by a backslash '\e') new-line character.
+\fBMACRO\fP, \fBPREREQUISITE\fP,
+and \fBTARGET\fP each represent a string of characters not
+including space or tab which respectively form the name of a macro,
+prerequisite or target.
+The name may itself be a macro expansion expression.
+A \fBLINE\fP can be continued over several physical lines by terminating it with
+a single backslash character.  Comments are initiated by the
+pound \fB#\fR character and extend to the end of line.
+All comment text is discarded, a '#' may be placed into the makefile text
+by escaping it with '\e' (ie. \e# translates to # when it is parsed).
+An exception to this occurs when a # is seen inside
+a recipe line that begins with a <tab> or is inside a group recipe.
+If you specify the \fB\-c\fP command line switch then this behavior is
+disabled and
+.B dmake
+will treat all # characters as start of comment indicators unless they
+are escaped by \e.
+A set of continued lines may be commented out by placing a single # at the
+start of the first line.
+A continued line cannot span more than one makefile.
+.PP
+\fBwhite space\fP is defined to be any combination of

+LINE. \fBNote\fP the special treatment of \e<nl> in macro definion and recipe
+lines below.
+When processing \fBmacro definition\fP lines,
+any amount of white space is allowed on either side of the macro operator
+and white space is stripped from both before and after the macro
+value string. A \e<nl> sequence in a macro definition is deleted from the
+macro value before assigning this value.
+During \fBrecipe expansion\fP the sequence \e<nl> is treated as white space 
+but is deleted from the final recipe string.
+You must escape the \e<nl> with another \e in order to get a \e at the end
+of a recipe or macro definition line.
+.PP
+When processing \fBtarget\fP definition lines,
+the recipe for a target must, in general, follow the first definition
+of the target (See the RULES AND TARGETS section for an exception), and
+the recipe may not span across multiple makefiles.
+Any targets and prerequisites found on a target definition line are taken
+to be white space separated tokens.
+The rule operator (\fIop\fP in SYNTAX section) is also considered
+to be a token but does not require
+white space to precede or follow it.  Since the rule operator begins with a `:',
+traditional versions of make do not allow the `:' character to
+form a valid target name.  \fBdmake\fP allows `:' to be present in
+target/prerequisite names as long as the entire target/prerequisite name is
+quoted.  For example:
+.sp
+\ta:fred : test
+.sp
+would be parsed as TARGET = a, PREREQUISITES={fred, :, test}, which
+is not what was intended.  To fix this you must write:
+.sp
+\t"a:fred" : test
+.sp
+Which will be parsed as expected.  Quoted target and prerequisite
+specifications may also contain white space thereby allowing the use of
+complex function macro expressions..
+See the EXAMPLES section for how to apply \fB"\fP quoting
+to a list of targets.
+.SH ATTRIBUTES
+.B dmake
+defines several target attributes.  Attributes may be
+assigned to a single target, a group of targets, or to all targets in the
+makefile.  Attributes are used to modify
+\fBdmake\fP actions during target update.
+The recognized attributes are:
+.sp
+.IP \fB.EPILOG\fP 1.2i
+Insert shell epilog code when executing a group recipe associated with
+any target having this attribute set.
+.IP \fB.ERRREMOVE\fP 1.2i
+Always remove any target having this attribute if an error is encountered
+while making them.  Setting this attribute overrides the .PRECIOUS attribute.
+.IP \fB.EXECUTE\fP 1.2i
+If the \-n flag was given then execute the recipe associated with any
+target having this attribute set.
+.IP \fB.FIRST\fP 1.2i
+Used in conjunction with .INCLUDE.  Terminates the inclusion with the first
+successfully included prerequisite.
+.IP \fB.GROUP\fP 1.2i
+Force execution of a target's recipe as a group recipe.
+.IP \fB.IGNORE\fP 1.2i
+Ignore an error when trying to make any target with this attribute set.
+.IP \fB.IGNOREGROUP\fP 1.2i
+Disable the special meaning of '[' to initiate a group recipe.
+.IP \fB.LIBRARY\fP 1.2i
+Target is a library.
+.IP \fB.MKSARGS\fP 1.2i
+If running in an MSDOS environment then use MKS extended argument passing
+conventions to pass arguments to commands.  Non-MSDOS
+environments ignore this attribute.
+.IP \fB.NOINFER\fP 1.2i
+Any target with this attribute set will not be subjected
+to transitive closure if it is inferred as a prerequisite 
+of a target whose recipe and prerequisites are being inferred.
+(i.e. the inference algorithm will not use any prerequisite with this attribute 
+set, as a target)
+If specified as '.NOINFER:' (ie. with no prerequisites or targets) then the
+effect is equivalent to specifying \fB\-T\fP on the command line.
+.IP \fB.NOSTATE\fP 1.2i
+Any target with this attribute set will not have command line flag
+information stored in the state file if .KEEP_STATE has been enabled.
+.IP \fB.PHONY\fP 1.2i
+Any target with this attribute set will have its recipe executed
+each time the target is made even if a file matching the target name can
+be located.  Any targets that have a .PHONY attributed target as a
+prerequisite will be made each time the .PHONY attributed prerequisite is
+made.
+.IP \fB.PRECIOUS\fP 1.2i
+Do not remove associated target under any circumstances.
+Set by default for any targets whose corresponding files exist in the file
+system prior to the execution of \fBdmake\fP.
+.IP \fB.PROLOG\fP 1.2i
+Insert shell prolog code when executing a group recipe associated with
+any target having this attribute set.
+.IP \fB.SEQUENTIAL\fP 1.2i
+Force a sequential make of the associated target's prerequisites. If set
+as a global attribute this implies setting MAXPROCESS=1.
+.IP \fB.SETDIR\fP 1.2i
+Change current working directory to specified directory when making the
+associated target.  You must
+specify the directory at the time the attribute is specified.  To do this
+simply give \fI.SETDIR=path\fP as the attribute.  \fIpath\fP is expanded and
+the result is used as the value of the directory to change to.
+If \fIpath\fP contains \fB$$@\fP then the name of the target to be built is
+used in computing the path to change directory to.
+If path is surrounded by single quotes then path is not expanded, and is used
+literally as the directory name.
+If the \fIpath\fP contains any `:' characters then the entire attribute string
+must be quoted using ".
+If a target having this attribute set also has the .IGNORE
+attribute set then if the change to the specified directory fails it will be
+ignored, and no error message will be issued.
+.IP \fB.SILENT\fP 1.2i
+Do not echo the recipe lines when making any target with this attribute set,
+and do not issue any warnings.
+.IP \fB.SWAP\fP 1.2i
+Under MSDOS
+when making a target with this attribute set swap the \fBdmake\fP executable
+to disk prior to executing the recipe line.  Also see the '%' recipe line
+flag defined in the RECIPES section.
+.IP \fB.SYMBOL\fP 1.2i
+Target is a library member and is an entry point into a module in the
+library.  This attribute is used only when searching a library for a target.
+Targets of the form lib((entry)) have this attribute set automatically.
+.IP \fB.USESHELL\fP 1.2i
+Force each recipe line of a target to be executed using a shell.
+Specifying this attribute is equivalent to specifying the '+' character at the
+start of each line of a non-group recipe.
+.IP \fB.UPDATEALL\fP 1.2i
+Indicates that all the targets listed in this rule are updated by the
+execution of the accompanying recipe.
+A common example is the production of the
+.I y.tab.c
+and
+.I y.tab.h
+files by
+.B yacc
+when it is run on a grammar.  Specifying .UPDATEALL in such a rule
+prevents the running of yacc twice, once for the y.tab.c file and once
+for the y.tab.h file.  .UPDATEALL targets that are specified in a single rule
+are treated as a single target and all timestamps are updated whenever any
+target in the set is made.  As a side-effect, \fBdmake\fP internally sorts
+such targets in ascending alphabetical order and the value of $@ is always
+the first target in the sorted set.
+.IP \fB.WINPATH\fP 1.2i
+Switch between default (POSIX) and Windows style path representation.
+(This attribute is specific for cygwin dmake executables and non-cygwin
+environments ignore this attribute.)
+.sp
+Under Cygwin it can be useful to generate Windows style paths (with
+regular slashes) instead of the default cygwin style (POSIX) paths
+for dmake's dynamic macros.
+The affected macros are $@, $*, $>, $?, $<, $&, $^ and $(MAKEDIR), $(PWD),
+$(TMD), $(TMPFILE) and the $(mktmp ...) function macro.
+This feature can be used to create DOS style path parameters
+for native W32 programs from dynamic macros.
+.sp
+\fBNote\fP that the Windows style paths use regular slashes ('/') instead
+of the usual Windows backslash ('\\') as directory separator to avoid quoting
+problems (after all it is still a cygwin \fBdmake\fP!) and cygwin, as well
+as native Windows, programs should have no problems using this (c:/foo/bar)
+path representation.
+.sp
+Example: Assuming the current target to be /tmp/mytarget the $@ macro
+without .WINPATH active expands to:
+.RS
+.sp
+.RS
+/tmp/mytarget
+.sp
+.RE
+With .WINPATH set it expands to:
+.sp
+.RS
+C:/cygwin/tmp/mytarget
+.RE
+.RE
+.LP
+All attributes are user setable and except for .UPDATEALL and .MKSARGS
+may be used in one of two forms.
+The .MKSARGS attribute is restricted to use as a global attribute, and
+the use of the .UPDATEALL attribute is restricted to rules
+of the second form only.
+.sp
+\tATTRIBUTE_LIST : \fItargets\fP
+.sp
+assigns the attributes specified by ATTRIBUTE_LIST to each target in
+.I targets
+or
+.sp
+\t\fItargets\fP ATTRIBUTE_LIST : ...
+.sp
+assigns the attributes specified by ATTRIBUTE_LIST to each target in
+.I targets.
+In the first form if
+.I targets
+is empty (ie. a NULL list), then the
+list of attributes will apply to all targets in the makefile
+(this is equivalent to the common Make construct of \fI".IGNORE :"\fP
+but has been modified to the notion of an attribute instead of
+a special target).
+Not all of the attributes have global meaning.
+In particular, .LIBRARY, .NOSTATE, .PHONY, .SETDIR, .SYMBOL and .UPDATEALL
+have no assigned global meaning.
+.PP
+Any attribute may be used with any target, even with the special targets.
+Some combinations are useless (e.g. .INCLUDE .PRECIOUS: ... ),
+while others are useful (e.g. .INCLUDE .IGNORE : "file.mk" will not complain
+if file.mk cannot be found using the include file search rules,
+see the section on SPECIAL TARGETS for a description of .INCLUDE).
+If a specified attribute will not be used with the special target a warning
+is issued and the attribute is ignored.
+.SH MACROS
+.B dmake
+supports six forms of macro assignment.
+.sp
+.IP "\fBMACRO = LINE\fP" 1.55i
+This is the most common and familiar form of macro assignment.  It assigns
+LINE literally as the value of MACRO.
+Future expansions of MACRO recursively expand its value.
+.IP "\fBMACRO *= LINE\fP" 1.55i
+This form behaves exactly as the simple '=' form with the exception that if
+MACRO already has a value then the assignment is not performed.
+.IP "\fBMACRO := LINE\fP" 1.55i
+This form differs from the simple '=' form in that it expands LINE
+prior to assigning it as the value of MACRO.
+Future expansions of MACRO do not recursively expand its value.
+.IP "\fBMACRO *:= LINE\fP" 1.55i
+This form behaves exactly as the ':=' form with the exception that if
+MACRO already has a value then the assignment and expansion are not performed.
+.IP "\fBMACRO += LINE\fP" 1.55i
+This form of macro assignment allows macro values to grow.  It takes the
+literal value of LINE and appends it to the previous value of MACRO separating
+the two by a single space.
+Future expansions of MACRO recursively expand its value.
+.IP "\fBMACRO +:= LINE\fP" 1.55i
+This form is similar to the '+=' form except that the value of LINE is expanded
+prior to being added to the value of MACRO.
+.PP
+Macro expressions specified on the command line allow the macro value
+to be redefined within the makefile only if the macro is defined using
+the '+=' and '+:=' operators.  Other operators will define a macro that cannot
+be further modified.
+.PP
+Each of the preceeding macro assignment operators may be prefixed by \fB!\fP
+to indicate that the assignment should be forced and that no warnings should
+be issued.  Thus, specifying \fB!\fP has the effect of silently forcing the
+specified macro assignment.
+.PP
+When \fBdmake\fP defines a non-environment macro it strips leading and
+trailing white space from the macro value.
+Macros imported from the environment via either the .IMPORT special
+target (see the SPECIAL TARGETS section), or the \fB\-e\fP, or \fB\-E\fP flags
+are an exception to this rule.  Their values are
+always taken literally and white space is never stripped.
+In addition, named macros defined using the .IMPORT special target do
+not have their values expanded when they are used within a makefile.
+In contrast, environment macros that are imported
+due to the specification of the \fB\-e\fP or \fB\-E\fP flags
+are subject to expansion when used.
+.PP
+To specify a macro expansion
+enclose the name in () or {} and precede it with a dollar sign $.
+Thus $(TEST) represents an expansion of the macro variable named TEST.
+If TEST is
+defined then $(TEST) is replaced by its expanded value.  If TEST is not
+defined then $(TEST) expands to the NULL string (this is equivalent to
+defining a macro as 'TEST=' ).  A short form may be used for single character
+named macros.  In this case the parentheses are optional, and $(I) is
+equivalent to $I.
+Macro expansion is recursive, hence, if the value string contains an expression
+representing a macro expansion, the expansion is performed.  Circular macro
+expansions are detected and cause an error to be issued.
+.PP
+When defining a macro the given macro name is first expanded before being used
+to define the macro.  Thus it is possible to define macros whose names
+depend on values of other macros.  For example, suppose CWD is defined as
+.sp
+\tCWD = $(PWD:b)
+.sp
+then the value of $(CWD) is the name of the current directory.
+This can be used to define macros specific to this directory, for
+example:
+.sp
+\t_$(CWD).prt = list of files to print...
+.sp
+The actual name of the defined macro is a function of the current directory.
+A construct such as this is useful when processing a hierarchy of directories
+using .SETDIR attributed targets and a collection of small distributed
+makefile stubs.
+.PP
+Macro variables may be defined within the makefile, on the command
+line, or imported from the environment.
+.PP
+.B \fBdmake\fR
+supports several non-standard macro expansions:
+The first is of the form:
+.RS
+.IP \fI$(macro_name:modifier_list:modifier_list:...)\fR
+.RE
+.LP
+where
+.I modifier_list
+may be a combination of:
+.RS
+.sp

+.Ii "d or D"
+\- directory portion of all path names

+\- file (including suffix) portion of path names

+.RE
+.fi
+Thus if we have the example:
+.RS
+test = d1/d2/d3/a.out f.out d1/k.out
+.RE

+.Ii "$(test:n)"
+\(-> d1/a.out "d1/file name.ext"

+.fi
+.PP
+If a token ends in a string composed from the value of the macro DIRBRKSTR
+(ie. ends in a directory separator string, e.g. '/' in UNIX) and you use the
+\fB:d\fP modifier then the expansion returns the directory name less the
+final directory separator string.  Thus successive pairs of :d modifiers
+each remove a level of directory in the token string.
+.PP
+The infered names of targets \fB:i\fP modifier returnes the actual filename
+associated to the target, see BINDING TARGETS. If the value is not a target or
+prerequisite the value is returned unchanged. For the following example:
+.RS
+test = aprog bprog
+.RE
+If aprog and bprog are targets or prerequisits and they are bound
+to /tmp/aprog and bprog (see .SOURCE special target) the macro expansion
+has the following effect:
+.RS
+.sp
+.Is "$(test:s/out/in/:f)   "
+.Ii "$(test:i)"
+\(-> /tmp/aprog bprog
+.RE
+.fi
+.PP
+The normalized path names \fB:n\fP modifier honors the setting of .WINPATH to
+determine the output format of the result.
+.PP
+The map escape codes modifier changes the following escape codes \ea => <bel>,
+\&\eb => <backspace>, \ef => <formfeed>, \en => <nl>, \er => <cr>,
+\&\et => <tab>, \ev => <vertical tab>, \e" => ", and \exxx => <xxx> where
+xxx is the octal representation of a character into the corresponding ASCII
+value.
+.PP
+The tokenization, prepend and append modifier may use the same escape codes
+that are supported by the map escape codes modifier in the string that is
+inserted, prepended or added by the respective macro modifier.
+These modifiers may quote this string to include otherwise problematic
+characters.  E.g. spaces, colons and parentheses.
+.PP
+The tokenization modifier takes all white space separated tokens from the
+macro value and separates them by the separator string.  Thus the
+expansion:
+.LP
+.RS
+.nf
+$(test:f:t"+\en")
+.RE
+produces:
+.RS
+a.out+
+f.out+
+k.out
+.fi
+.RE
+.PP
+The prefix operator \fB^\fP takes all white space separated tokens from the

+.RE
+produces:

+.nf
+$(test:b:+.c)
+.RE
+produces:
+.RS
+a.c f.c k.c
+.fi
+.RE
+.PP
+The next non-standard form of macro expansion allows for recursive macros.
+It is possible to specify a $(\fImacro_name\fR) or ${\fImacro_name\fR} expansion
+where \fImacro_name\fR contains more $( ... ) or ${ ... } macro expansions
+itself.
+.PP
+For example $(CC$(_HOST)$(_COMPILER)) will first expand CC$(_HOST)$(_COMPILER)
+to get a result and use that result as the name of the macro to expand.
+This is useful for writing a makefile for more than one target
+environment.  As an example consider the following hypothetical case. 
+Suppose that _HOST and _COMPILER are imported from the environment
+and are set to represent the host machine type and the host compiler
+respectively.
+.RS
+.sp
+.nf
+CFLAGS_VAX_CC = \-c \-O  # _HOST == "_VAX", _COMPILER == "_CC"
+CFLAGS_PC_MSC = \-c \-ML # _HOST == "_PC",  _COMPILER == "_MSC"
+.sp
+# redefine CFLAGS macro as:
+.sp
+CFLAGS := $(CFLAGS$(_HOST)$(_COMPILER))
+.fi
+.sp
+.RE
+This causes CFLAGS to take on a value that corresponds to the
+environment in which the make is being invoked.
+.PP
+The final non-standard macro expansion is of the form:
+.RS
+.sp
+string1{token_list}string2
+.RE
+.LP
+where string1, string2 and token_list are expanded.  After expansion,
+string1 is prepended to each token found in token_list and
+string2 is appended to each resulting token from the previous prepend.
+string1 and string2 are not delimited by white space
+whereas the tokens in token_list are.
+A null token in the token list 
+is specified using "".
+Thus using another example we have:
+.RS
+.sp
+.Is "test/{f1  f2}.o    "
+.Ii "test/{f1 f2}.o"
+--> test/f1.o test/f2.o
+.Ii "test/ {f1 f2}.o"

+test/d1/f1.o test/d1/f2.o
+test/d2/f1.o test/d2/f2.o
+.sp
+.RE
+.fi
+This last expansion is activated only when the first characters of
+\fItoken_list\fP
+appear immediately after the opening '{' with no intervening white space.
+The reason for this restriction is the following incompatibility with
+Bourne Shell recipes.  The line
+.RS
+.sp
+{ echo hello;}
+.sp
+.RE
+is valid /bin/sh syntax; while
+.RS
+.sp
+{echo hello;}
+.sp
+.RE
+.fi
+is not. Hence the latter triggers the enhanced macro expansion while the former
+causes it to be suppressed.
+See the SPECIAL MACROS section for a description of the special macros that
+\fBdmake\fP defines and understands.
+.SH "RULES AND TARGETS"
+A makefile contains a series of entries that specify dependencies.
+Such entries are called \fItarget/prerequisite\fP or \fIrule\fP definitions.

+any targets defined by the rule.
+Whenever

+different recipe for updating the target.  
+Any such target is made if any of the definitions
+find it to be out of date
+with respect to the related prerequisites
+and the corresponding recipe is used to update the
+target.  By definition all '::' recipes that are found to be out of date for
+are executed.
+.sp 
+In the following simple example, each rule has a `::' \fIruleop\fP.  In such an
+operator we call the first `:' the operator, and the second `:' the modifier.
+.sp
+.nf
+a.o :: a.c b.h
+   first recipe for making a.o
+
+a.o :: a.y b.h
+   second recipe for making a.o
+.fi
+.sp
+If a.o is found to be out of date with respect to a.c then the first recipe
+is used to make a.o.  If it is found out of date with respect to a.y then
+the second recipe is used.  If a.o is out of date with respect to
+b.h then both recipes are invoked to make a.o.
+In the last case the order of invocation corresponds to the order in which the
+rule definitions appear in the makefile.
+.IP \fB|\fP
+Is defined only for PERCENT rule target definitions.  When specified it
+indicates that the following construct should be parsed using the old
+semantinc meaning:
+.sp
+.nf
+%.o :| %.c %.r %.f ; some rule
+.sp
+is equivalent to:
+.sp
+%.o : %.c ; some rule
+%.o : %.r ; some rule
+%.o : %.f ; some rule
+.fi
+.PP
+Targets defined using a single `:' operator
+with a recipe may be redefined again with a new recipe by using a
+`:' operator with a `:' modifier.
+This is equivalent to a target having been
+initially defined with a rule using a `:' modifier.
+Once a target is defined using a `:'
+modifier it may not be defined again with a recipe using only the `:' operator
+with no `:' modifier.  In both cases the use of a `:' modifier creates a new
+list of prerequisites and makes it the current prerequisite list for the target.
+The `:' operator with no recipe always modifies the current list
+of prerequisites.
+Thus assuming each of the following definitions has a recipe attached, then:
+.RS
+.sp
+.nf
+joe :  fred ...	(1)
+joe :: more ...	(2)
+.sp
+and
+.sp
+joe :: fred ...	(3)
+joe :: more ...	(4)
+.sp
+.fi
+.RE
+are legal and mean:  add the recipe associated with (2), or (4) to the set
+of recipes for joe, placing them after existing recipes for
+making joe.
+The constructs:
+.RS
+.sp
+.nf
+joe :: fred ...	(5)
+joe : more ...	(6)
+.sp
+and
+.sp
+joe : fred ...	(7)
+joe : more ...	(8)
+.sp
+.fi
+.RE
+are errors since we have two sets of perfectly good recipes for
+making the target.
+.PP
+.I prerequisites
+is a possibly empty list of targets that must be brought up to date before
+making the current target.
+.PP
+.I recipe
+is a short form and allows the user to specify short rule definitions
+on a single line.
+It is taken to be the first recipe line in a larger recipe
+if additional lines follow the rule definition.
+If the semi-colon is present but the recipe line is empty (ie. null string)
+then it is taken
+to be an empty rule.  Any target so defined causes target to be treated
+as a virtual target, see VIRTUAL TARGETS below.
+.SH "RECIPES"
+The traditional format used by most versions of Make defines the recipe
+lines as arbitrary strings that may contain macro expansions.  They
+follow a rule definition line and may be spaced
+apart by comment or blank lines.
+The list of recipe lines defining the recipe is terminated by a new target
+definition, a macro definition, or end-of-file.
+Each recipe line
+.B MUST
+begin with a \fB<TAB>\fP character (or \fBspaces\fP, see \fB.NOTABS\fP)
+which may optionally be followed with one or all the following
+.I recipe property
+characters 
+.IR "'@%+\-'"
+which affect the recipe execution:
+.IP "'\-'"
+indicates that non-zero exit values (ie. errors)
+are to be ignored when this recipe line is executed.
+.IP "'\+'"
+indicates that the current recipe line is to be executed using the shell. Group recipes implicitely ignore this property.
+.IP "'%'"
+indicates that
+.B dmake
+should swap itself out to secondary storage (MSDOS only) before running the
+recipe.
+.IP "'@'"
+indicates that the recipe line should NOT be echoed to the terminal prior to
+being executed.
+.IP "'@@'"
+is a stronger version of the previous property. The recipe line and the
+output (stdout and stderr) of the executed recipe are NOT shown on the
+terminal.
+.LP
+Each property is off by default
+(ie. by default, errors are significant, commands are echoed, no swapping is
+done and a shell is
+used only if the recipe line contains a character found in the value of the
+SHELLMETAS macro).
+Global settings activated via command line options or special attribute or
+target names may also affect these settings.
+An example recipe:
+.sp
+.RS
+.nf
+target :
+.RS
+first recipe line
+second recipe line, executed independent of first.
+@a recipe line that is not echoed
+-and one that has errors ignored
+%and one that causes dmake to swap out
++and one that is executed using a shell.
+.RE
+.fi
+.RE
+.PP
+The second and new format of the recipe block begins the block with the
+character '[' (the open group character) in the last non-white space
+position of a line, and terminates the
+block with the character ']' (the close group character)
+in the first non-white space position of a line.
+In this form each recipe line need not have a leading TAB.  This is
+called a recipe group.  Groups so defined are fed intact as a single
+unit to a shell for execution whenever the corresponding target needs to
+be updated.  If the open group character '[' is preceded
+by one or all of the
+.I recipe properties
+(\-, %, @ and @@)
+then they apply to the entire group in the same way that they
+apply to single recipe lines.  You may also specify '+' but it is
+redundant as a shell is already being used to run the recipe.
+See the MAKING TARGETS section for a description of how
+.B dmake
+invokes recipes.
+Here is an example of a group recipe:
+.sp
+.RS
+.nf
+target :
+[
+   first recipe line
+   second recipe line
+   tall of these recipe lines are fed to a
+   single copy of a shell for execution.
+]
+.fi
+.RE
+.sp
+.SH "BUILTIN COMMANDS"
+.B dmake
+supports some builtin commands. An optional leading '+' describes that
+the builtin can be used also when being executed in a shell otherwise it
+is only implemented when used directly. Remember that if a character of the
+recipe is found in the SHELLMETAS macro the execution of the recipe in a
+shell is forced.
+.IP "[\fB+\fP]\fBnoop\fP [\fBsomething\fP]"
+The  \fBnoop\fP internal command always returns success if used but it is
+not executed even though the rest of the commandline is evaluated.
+This command can be used to evaluate macro expansions at the runtime of the
+recipe without starting a real commmand.
+.IP "[\fB+\fP]<empty recipe>
+If an empty recipe line is encountered it is not executed. This sounds
+more trivial than it really is because the recipe could consist of
+macros that evaluated to empty or whitespace only strings.
+.IP "\fBecho\fP [\fB-n\fP] \fBdata\fP"
+This internal command prints data (with all leading whitespace removed, but
+otherwise literally) to stdout. If the '-n' switch is given no trailing
+newline is printed. Note that no quoting is removed nor that escape sequences
+are handled.
+.PP
+No special treatment of buildin commands for group recipes is implemented
+even though the <empty recipe> will most propably also not be evaluated by
+most shells that can be used to handle the recipe groups.
+.SH "TEXT DIVERSIONS"
+.B dmake
+supports the notion of text diversions.
+If a recipe line contains the macro expression
+.RS
+.sp
+$(mktmp[,[\fIfile\fP][,\fItext\fP]] \fIdata\fP)
+.sp
+.RE
+then all text contained in the \fIdata\fP expression is expanded and
+is written to a temporary file.  The \fIdata\fP in the file will always
+be terminated from a new line character.  The \fIfile\fP parameter can
+be used to override the name of the temporary file. If its expanded value
+is not empty it will be used instead of the unique and thread safe file
+name that otherwise would be generated internally.  The return
+value of the macro is the name of the temporary file unless the \fItext\fP
+parameter is defined. In this case the return value is the expanded value
+of \fItext\fP.
+.PP
+.I data
+can be any text and must be separated from the 'mktmp' portion of the
+macro name by white-space.  The only restriction on the data text is that
+it must contain a balanced number of parentheses of the same kind as are
+used to initiate the $(mktmp ...) expression.  For example:
+.RS
+.sp
+$(mktmp $(XXX))
+.sp
+.RE
+is legal and works as expected, but:
+.RS
+.sp
+$(mktmp text (to dump to file)
+.sp
+.RE
+is not legal.  You can achieve what you wish by either defining a macro that
+expands to '(' or by using {} in the macro expression; like this:
+.RS
+.sp
+${mktmp text (to dump to file}
+.sp
+.RE
+Since the temporary file is opened when the
+macro containing the text diversion expression is expanded, diversions may
+be nested and any diversions that are created as part of ':=' macro
+expansions persist for the duration of the
+.B dmake
+run.
+If the \fIdata\fP text is to contain new lines the map escape codes macro
+expasion can be used.  For example the expression:
+.RS
+.sp
+.nf
+mytext:=this is a\entest of the text diversion
+all:
+	cat $(mktmp $(mytext:m))
+.fi
+.sp
+.RE
+is replaced by:
+.RS
+.sp
+cat /tmp/mk12294AA
+.sp
+.RE
+where the temporary file contains two lines both of which are terminated
+by a new-line.
+A second more illustrative example generates a response file to an MSDOS
+link command:
+.RS
+.sp
+.nf
+OBJ = fred.obj mary.obj joe.obj
+all : $(OBJ)
+	link @$(mktmp $(^:t"+\en"))
+.fi
+.sp
+.RE
+The result of making `all' in the second example is the command:
+.RS
+.sp
+link @/tmp/mk02394AA
+.sp
+.RE
+where the temporary file contains:
+.RS
+.sp
+.nf
+fred.obj+
+mary.obj+
+joe.obj
+.fi
+.sp
+.RE
+The last line of the file is terminated by a new-line which is always
+inserted at the end of the \fIdata\fP string.
+.PP
+If the optional \fIfile\fP specifier is present it can be used to specify
+the name of the temporary file to create.  An example that would be useful
+for MSDOS users with a Turbo-C compiler
+.RS
+.sp
+$(mktmp,turboc.cfg $(CFLAGS))
+.sp
+.RE
+will place the contents of CFLAGS into a local \fIturboc.cfg\fP file.
+The second optional argument, \fItext\fP, if present alters the name
+of the value returned by the $(mktmp ...) macro.
+.PP
+Under MS-DOS text diversions may be a problem.  Many DOS tools require
+that path names which contain directories use the \e character to delimit
+the directories.  Some users however wish to use the '/' to delimit pathnames
+and use environments that allow them to do so.
+The macro USESHELL is set to "yes" if the
+current recipe is forced to use a shell via the .USESHELL or '+' directives,
+otherwise its value is "no".
+The
+.B dmake
+startup files define the macro DIVFILE whose value is either the
+value of TMPFILE or the value of TMPFILE edited to replace any '/' characters
+to the appropriate value based on the current shell and whether it will be
+used to execute the recipe.
+.PP
+Previous versions of
+.B dmake
+defined text diversions using <+, +> strings,
+where <+ started a text diversion and +> terminated one.
+.B dmake
+is backward compatible with this construct only
+if the <+ and +> appear literally
+on the same recipe line or in the same macro value string.  In such instances
+the expression:
+.sp
+\t<+data+>
+.sp
+is mapped to:
+.sp
+\t$(mktmp data)
+.sp
+which is fully output compatible with the earlier construct.  <+, +>
+constructs whose text spans multiple lines must be converted by hand to use
+$(mktmp ...).
+.PP
+If the environment variable TMPDIR is defined then the
+temporary file is placed into the directory specified by that variable.
+A makefile can modify the location of temporary files by
+defining a macro named TMPDIR and exporting it using the .EXPORT special
+target.
+.SH "VIRTUAL TARGETS"
+.B Dmake
+allows to define targets with the sole purpose to enforce a dependency
+chain that are unable to create the target, hence virtual targets.
+When \fBdmake\fP tries to make a target, but only finds a target definition
+without recipe lines, it would normally issues
+a \fB"Don't know how to make ..."\fP error message, but if a target rule is
+terminated by a semicolon and has no following recipe lines,
+or if it has no recipe lines, but defines prerequisites,
+or if the AUGMAKE mode is enabled (see the COMPATIBILITY section for details),
+the target is treated as a virtual target and the error is suppressed. In
+addition to this, if the default target does not have recipe lines it is also
+treated as a virtual target.
+.PP
+Virtual targets should not have a corresponding file therefore
+they inherit the time of their newest prerequisite if they have prerequisites,
+otherwise they get the current time assigned when being made.
+If the virtual target has a corresponding file a warning is issued, but the
+time stamp of that file is taken into account. The virtual target uses the
+time stamp of the corresponding file if it is newer than the one determined
+by the previous rule.
+.SH "SPECIAL TARGETS"
+This section describes the special targets that are recognized by \fBdmake\fP.
+Some are affected by attributes and others are not.
+.IP \fB.ERROR\fP 1.4i
+If defined then the recipe associated with this target is executed
+whenever an error condition is detected by \fBdmake\fP.  All attributes that
+can be used with any other target may be used with this target.  Any
+prerequisites of this target will be brought up to date during its processing.
+NOTE:  errors will be ignored while making this target, in extreme cases this
+may cause some problems.
+.IP \fB.EXIT\fP 1.4i
+If this target is encountered while parsing a makefile then the parsing of the
+makefile is immediately terminated at that point.
+.IP \fB.EXPORT\fP 1.4i
+All prerequisites associated with this target are assumed to
+correspond to macro names and they and their values
+are exported to the environment as environment strings at the point in
+the makefile at which this target appears.
+Any attributes specified with this target are ignored.
+Only macros which have been assigned a value in the makefile prior to the
+export directive are exported, macros as yet undefined
+or macros whose value contains any of the characters "+=:*"
+are not exported.
+.sp
+Note that macros that are not expanded during the macro assignment and contain
+other macros will be written into the environment containing these other
+macros in the form of $(macroname).
+.IP \fB.IMPORT\fP 1.4i
+Prerequisite names specified for this target are searched for in the
+environment and defined as macros with their value taken from the environment.
+If the special name \fB.EVERYTHING\fP is used as a prerequisite name then
+all environment variables defined in the environment are imported.
+The functionality of the \fB\-E\fP flag can be forced by placing the construct
+\&\fI.IMPORT : .EVERYTHING\fP at the start of a makefile.  Similarly, by
+placing the construct at the end, one can emulate the effect of the \fB\-e\fP
+command line flag.
+If a prerequisite name cannot be found in the environment
+an error message is issued.
+\&.IMPORT accepts the .IGNORE attribute.  When given, it causes \fBdmake\fP
+to ignore the above error.
+See the MACROS section for a description of the processing of imported macro
+values.
+.IP \fB.INCLUDE\fP 1.4i
+Parse another makefile just as if it had been located at the point of the
+\&.INCLUDE in the current makefile.
+The list of prerequisites gives the list of
+makefiles to try to read.  If the list contains multiple makefiles then they
+are read in order from left to right.  The following search rules are used
+when trying to locate the file.  If the filename is surrounded by " or just
+by itself then it is searched for in the current directory.  If it is not
+found it is then searched for in each of the directories specified
+as prerequisites of the \&.INCLUDEDIRS special target.
+If the file name is surrounded by < and >, (ie.
+<my_spiffy_new_makefile>) then it is searched for only in the directories
+given by the .INCLUDEDIRS special target.  In both cases if the file name is a
+fully qualified name starting at the root of the file system then it is only
+searched for once, and the .INCLUDEDIRS list is ignored.
+If .INCLUDE fails to find the file it invokes the inference engine to
+try to infer and hence make the file to be included.  In this way the
+file can be checked out of an RCS repository for example.
+\&.INCLUDE accepts
+the .IGNORE, .SETDIR, and .NOINFER attributes.
+If the .IGNORE attribute is given and the file
+cannot be found then \fBdmake\fP continues processing,
+otherwise an error message is generated.
+If the .NOINFER attribute is given and the file
+cannot be found then \fBdmake\fP will not attempt to
+\fIinfer and make\fP the file.
+The .SETDIR attribute causes
+.B dmake
+to change directories to the specified directory prior to attempting the
+include operation.  If all fails \fBdmake\fP attempts to \fImake\fP the file
+to be included.  If making the file fails then \fBdmake\fP terminates unless
+the .INCLUDE directive also specified the .IGNORE attribute.
+If .FIRST is specified along with .INCLUDE then \fBdmake\fP attempts to
+include each named prerequisite and will terminate the inclusion with the
+first prerequisite that results in a successful inclusion.
+.IP \fB.INCLUDEDIRS\fP 1.4i
+The list of prerequisites specified for this target defines the set of
+directories to search when trying to include a makefile.
+.IP \fB.KEEP_STATE\fP 1.4i
+This special target is a synonym for the macro definition
+.sp
+\&\t.KEEP_STATE := _state.mk
+.sp
+It's effect is to turn on STATE keeping and to define \fI_state.mk\fP
+as the state file.
+.IP \fB.MAKEFILES\fP 1.4i
+The list of prerequisites is the set of files to try to read as the default
+makefile.  By default this target is defined as: 
+.sp
+\t\&.MAKEFILES : makefile.mk Makefile makefile
+.sp
+.IP \fB.REMOVE\fP 1.4i
+The recipe of this target is used whenever \fBdmake\fP needs to remove
+intermediate targets that were made but do not need to be kept around.
+Such targets result from the application of transitive closure on the
+dependency graph.
+.IP \fB.ROOT\fP 1.4i
+The internal root of the dependency graph, see section STARTUP for details.
+.IP \fB.SOURCE\fP 1.4i
+The prerequisite list of this target defines a set of directories to check
+when trying to locate a target file name.  See the section on BINDING of
+targets for more information.
+.IP \fB.SOURCE.suff\fP 1.4i
+The same as .SOURCE, except that the .SOURCE.suff list is searched first when
+trying to locate a file matching the a target whose name ends in the suffix
+\&.suff.
+.IP \fB.SUFFIXES\fP 1.4i
+This deprecated special target has no special meaning. Avoid its use.
+.IP \fB.TARGETS\fP 1.4i
+The internal targets that all user defined targets are prerequisites of,
+see section STARTUP for details.
+.PP
+There are a few targets that are "slightly" special:
+.RS
+.nf
+
+\&\fB.INIT\fP
+\&\fB.DONE\fP
+
+.fi
+.RE
+These targets exist because of historical reasons, see the usage of .INIT
+and .DONE in section "STARTUP", they can be used and defined as ordinary
+targets but are special in the sense that even though they start with a `.'
+they are not treated as a .<suffix> meta target (See the AUGMAKE META RULES
+section for details).
+.PP
+.B Please note
+that self defined targets shouldn't use the prefix `.' as they would be
+handled as .<suffix> meta targets and dmake most propably would complain
+about this.
+.PP
+In addition to the special targets above,
+several other forms of targets are recognized and are considered special,
+their exact form and use is defined in the sections that follow.
+.SH "SPECIAL MACROS"
+.B dmake
+defines a number of special macros.  They are divided into three classes:
+control macros, run-time macros, and function macros.
+The control macros are used by
+.B dmake
+to configure its actions, and are the preferred method of doing so.
+In the case when a control macro has the same function as a special 
+target or attribute they share the same name as the special target or
+attribute.
+The run-time macros are defined when
+.B dmake
+makes targets and may be used by the user inside recipes.
+The function macros provide higher level functions dealing with macro
+expansion and diversion file processing.
+.SH "CONTROL MACROS"
+To use the control macros simply assign them a value just like any other
+macro.  The control macros are divided into three groups:
+string valued macros, character valued macros, and boolean valued macros.
+.PP
+The following are all of the string valued macros.
+This list is divided into two groups.  The first group gives the string
+valued macros that are defined internally and cannot be directly set by the
+user.
+.IP \fBABSMAKECMD\fP 1.6i
+\fBWarning!\fP This macro's value is differently defined for a native Windows
+dmake executable (compiled with MS Visual C++ or MinGW) and dmake for other
+operating systems or build with other compilers.
+.sp
+In the first case its value is the absolute filename of the executable of
+the current dmake process, otherwise it is defined as the NULL string.
+.IP \fBINCDEPTH\fP 1.6i
+This macro's value is a string of digits representing
+the current depth of makefile inclusion.
+In the first makefile level this value is zero.
+.IP \fBMFLAGS\fP 1.6i
+Is the list of flags
+that were given on the command line including a leading switch character.
+The \-f flag is not included in this list.
+.IP \fBMAKECMD\fP 1.6i
+Is the name with which \fBdmake\fP was invoked.
+.IP \fBMAKEDIR\fP 1.6i
+Is the full path to the initial directory in which
+.B dmake
+was invoked.
+.IP \fBMAKEFILE\fP 1.6i
+Contains the string "\-f \fImakefile\fP" where, \fImakefile\fP is the name
+of initial user makefile that was first read.
+.IP \fBMAKEFLAGS\fP 1.6i
+Is the same as $(MFLAGS) but has no leading switch
+character. (ie. MFLAGS = \-$(MAKEFLAGS))
+.IP \fBMAKEMACROS\fP 1.6i
+Contains the complete list of macro expressions that were specified on the
+command line.
+.IP \fBMAKETARGETS\fP 1.6i
+Contains the name(s) of the target(s), if any, that were
+specified on the command line.
+.IP \fBMAKEVERSION\fP 1.6i
+Contains a string indicating the current \fBdmake\fP version number.
+.IP \fBMAXPROCESSLIMIT\fP 1.6i
+Is a numeric string representing the maximum number of processes that 
+\fBdmake\fP can use when making targets using parallel mode.
+.IP \fBNULL\fP 1.6i
+Is permanently defined to be the NULL string.
+This is useful when comparing a conditional expression to an NULL value.
+.IP \fBPWD\fP 1.6i
+Is the full path to the
+current directory in which make is executing.
+.IP \fBSPACECHAR\fP 1.6i
+Is permanently defined to contain one space character. This is useful
+when using space characters in function macros, e.g. subst, that
+otherwise would get deleted (leading/trailing spaces) or for using
+spaces in function macro parameters.
+.IP \fBTMPFILE\fP 1.6i
+Is set to the name of the most recent temporary file opened by \fBdmake\fP.
+Temporary files are used for text diversions and for group recipe processing.
+.IP \fBTMD\fP 1.6i
+Stands for "To Make Dir", and
+is the path from the present directory (value of $(PWD)) to the directory
+that \fBdmake\fP was started up in (value of $(MAKEDIR)). If the present
+directory is the directory that \fBdmake\fP was started up in TMD will be
+set to the relative path ".". This allows to create valid paths by prepending
+$(TMD)$(DIRSEPSTR) to a relative path.
+This macro is modified when .SETDIR attributes are processed.
+TMD will usually be a relative path with the following two exceptions. If the
+relative path would go up until the root directory or if different drive
+letters (DOS file system) make a relative path impossible the absolute path
+from MAKEDIR is used.
+.IP \fBUSESHELL\fP 1.6i
+The value of this macro is set to "yes" if the current recipe is forced to
+use a shell for its execution via the .USESHELL or '+' directives, its value
+is "no" otherwise.
+.sp
+.PP
+The second group of string valued macros control
+.B dmake
+behavior and may be set by the user.
+.IP \fB.DIRCACHE\fP 1.6i
+If set to "yes" enables the directory cache (this is the default).  If set to
+"no" disables the directory cache (equivalent to -d command-line flag).
+.IP \fB.DIRCACHERESPCASE\fP 1.6i
+If set to "yes" causes the directory cache, if enabled, to respect
+file case, if set to "no" files are cached case insensitive.
+By default it is set to "no" on Windows as the filesystems on
+this operating system are case insensitive and set to "yes" for all
+other operating systems. The default can be overriden, if desired.
+.sp
+\fBNote:\fP Using case insensitive directory caching on case sensitive
+file systems is a \fBBAD\fP idea. If in doubt use case sensitive
+directory caching even on case insensitive file systems as the
+worst case in this scenario is that /foo/bar/ and /foo/BAR/ are
+cached separately (with the same content) even though they are
+the same directory. This would only happen if different targets
+use different upper/lower case spellings for the same directory
+and that is \fBnever\fP a good idea.
+.IP \fBNAMEMAX\fP 1.6i
+Defines the maximum length of a filename component.  The value of the variable
+is initialized at startup to the value of the compiled macro NAME_MAX.  On
+some systems the value of NAME_MAX is too short by default.  Setting a new
+value for NAMEMAX will override the compiled value.
+.IP \fB.NOTABS\fP 1.6i
+When set to "yes" enables the use of spaces as well as <tabs> to begin
+recipe lines.
+By default a non\-group recipe is terminated by a line without any leading
+white\-space or by a line not beggining with a <tab> character.
+Enabling this mode modifies the first condition of
+the above termination rule to terminate a
+non\-group recipe with a line that contains only white\-space.
+This mode does not effect the parsing of group recipes bracketed by [].
+.IP \fBAUGMAKE\fP 1.6i
+If set to "yes" value will enable the transformation of special
+meta targets to support special AUGMAKE inferences (See the "AUGMAKE
+META RULES" and "COMPATIBILITY" sections).
+.IP \fBDIRBRKSTR\fP 1.6i
+Contains the string of chars used to terminate
+the name of a directory in a pathname.
+Under UNIX its value is "/", under MSDOS its value is "/\e:".
+.IP \fBDIRSEPSTR\fP 1.6i
+Contains the string that is used to separate directory components when
+path names are constructed.  It is defined with a default value at startup.
+.IP \fBDIVFILE\fP 1.6i
+Is defined in the startup file and gives the name that should be returned for
+the diversion file name when used in
+$(mktmp ...) expansions, see the TEXT DIVERSION section for details.
+.IP \fB.KEEP_STATE\fP 1.6i
+Assigning this macro a value tells
+.B dmake
+the name of the state file to use and turns on the keeping of state
+information for any targets that are brought up to date by the make.
+.IP \fBGROUPFLAGS\fP 1.6i
+This macro gives the set of flags to pass to the shell when
+invoking it to execute a group recipe.  The value of the macro is the
+list of flags with a leading switch indicator.  (ie. `\-' under UNIX)
+.IP \fBGROUPSHELL\fP 1.6i
+This macro defines the full
+path to the executable image to be used as the shell when
+processing group recipes.  This macro must be defined if group recipes are
+used.  It is assigned a default value in the startup makefile.  Under UNIX
+this value is /bin/sh.
+.IP \fBGROUPSUFFIX\fP 1.6i
+If defined, this macro gives the string to use as a suffix
+when creating group recipe files to be handed to the command interpreter.
+For example, if it is defined as .sh, then all
+temporary files created by \fBdmake\fP will end in the suffix .sh.
+Under MSDOS if you are using command.com as your GROUPSHELL, then this suffix
+must be set to .bat in order for group recipes to function correctly.
+The setting of GROUPSUFFIX and GROUPSHELL is done automatically for
+command.com in the startup.mk files.
+.IP \fBMAKE\fP 1.6i
+Is defined in the startup file by default.
+Initially this macro is defined to have the value "$(MAKECMD) $(MFLAGS)".
+The string $(MAKE) is recognized when using the \-n switch.
+.IP \fBMAKESTARTUP\fP 1.6i
+This macro defines the full path to the initial startup
+makefile.  Use the \fB\-V\fP command line option to discover its initial
+value.
+.IP \fBMAXLINELENGTH\fP 1.6i
+This macro defines the maximum size of a single line of
+makefile input text.  The size is specified as a number, the default value
+is defined internally and is shown via the \fB\-V\fP option.
+A buffer of this size plus 2 is allocated for reading makefile text.  The
+buffer is freed before any targets are made, thereby allowing files containing
+long input lines to be processed without consuming memory during the actual
+make.
+This macro can only be used to extend the line length beyond it's default
+minimum value.
+.IP \fBMAXPROCESS\fP 1.6i
+Specify the maximum number of child processes to use when making targets.
+The default value of this macro is "1" and its value cannot exceed the value
+of the macro MAXPROCESSLIMIT.  Setting the value of MAXPROCESS on the command
+line or in the makefile is equivalent to supplying a corresponding value to
+the -P flag on the command line. If the global .SEQUENTIAL attribute is set
+(or the -S command line switch is used) the value of MAXPROCESS is fixed
+to "1" and cannot be changed.
+.IP \fBOOODMAKEMODE\fP 1.6i
+This macro enables a special compatibility mode needed by the OpenOffice.org
+build system. If set, the switch disables the removal of leading './' path
+elements during target filename normalization (See BINDING TARGETS). If './'
+appear in the pathname, but not at the beginning of it, they are still
+removed by the normalization. Please note that targets that are given on the
+command line are going to be registered as default targets \fBafter\fP the
+startup file is read.
+.IP \fBPREP\fP 1.6i
+This macro defines the number of iterations to be expanded
+automatically when processing % rule definitions of the form:
+.sp
+% : %.suff
+.sp
+See the sections on PERCENT(%) RULES for details on how PREP is used.
+.IP \fBSHELL\fP 1.6i
+This macro defines the full path to the executable
+image to be used as the shell when
+processing single line recipes.  This macro must be defined if recipes
+requiring the shell for execution are to be used.
+It is assigned a default value in the startup makefile.
+Under UNIX this value is /bin/sh.
+.IP \fBSHELLCMDQUOTE\fP 1.6i
+This macro can be used to add additional characters before and after the
+command string that is passed to the shell defined by the SHELL macro.
+If needed, like for \fIcmd.exe\fP and \fIcommand.com\fP, it is assigned
+a value in the startup file.
+.IP \fBSHELLFLAGS\fP 1.6i
+This macro gives the set of flags to pass to the shell when
+invoking it to execute a single line recipe.  The value of the macro is the
+list of flags with a leading switch indicator.  (ie. `\-' under UNIX)
+.IP \fBSHELLMETAS\fP 1.6i
+Each time
+.B dmake
+executes a single recipe line (not a group recipe) the line is
+searched for any occurrence of a character defined in the value of SHELLMETAS.
+If such a character is found the recipe line is defined to require a shell
+to ensure its correct execution.  In such instances
+a shell is used to invoke the recipe line.
+If no match is found the recipe line is executed without the use of a shell.
+.sp
+.PP
+There is only one character valued macro defined by \fBdmake\fP:
+\fBSWITCHAR\fP contains the switch character used
+to introduce options on command lines.  For UNIX its value is `\-', and for
+MSDOS its value may be `/' or `\-'.
+The macro is internally defined and is not user setable.
+The MSDOS version of \fBdmake\fP attempts to first extract SWITCHAR from an
+environment variable of the same name.  If that fails it then attempts to
+use the undocumented getswitchar system call, and returns the result of
+that.  Under MSDOS version 4.0 you must set the value of the environment
+macro SWITCHAR to '/' to obtain predictable behavior.
+.PP
+All boolean macros currently understood by 
+.B dmake
+correspond directly to the previously defined attributes.
+These macros provide
+a second way to apply global attributes, and represent the
+preferred method of doing so.  They are used by assigning them a
+value.  If the value is not a NULL string then the boolean condition
+is set to on.
+If the value is a NULL string then the condition is set to off.
+There are five conditions defined and they correspond directly to the
+attributes of the same name.  Their meanings are defined in the ATTRIBUTES
+section above.
+The macros are:
+\&\fB.EPILOG\fP,
+\&\fB.IGNORE\fP,
+\&\fB.MKSARGS\fP,
+\&\fB.NOINFER\fP,
+\&\fB.PRECIOUS\fP,
+\&\fB.PROLOG\fP,
+\&\fB.SEQUENTIAL\fP,
+\&\fB.SILENT\fP,
+\&\fB.SWAP\fP, and
+\&\fB.USESHELL\fP.
+Assigning any of these a non NULL value will globally set
+the corresponding attribute to on.
+.SH "RUNTIME MACROS"
+These macros are defined
+when \fBdmake\fP is making targets, and may take on different values for each
+target.  \fB$@\fP is defined to be the full target name, \fB$?\fP is the
+list of all out of date prerequisites, except for the \fB!\fP ruleop, in
+which case it is set to the current build
+prerequisite instead.  \fB$&\fP is the list of all
+prerequisites, \fB$>\fP is the name of the library if the current target is a
+library member, and
+\fB$<\fP is the list of prerequisites specified in the current rule.
+If the current target had a recipe inferred then \fB$<\fP is the name of the
+inferred prerequisite even if the target had a list of prerequisites supplied
+using an explicit rule that did not provide a recipe.  In such situations
+\fB$&\fP gives the full list of prerequisites.
+.PP
+\fB$*\fP is defined as
+\fB$(@:db)\fP when making targets with explicit recipes and is defined as the
+value of % when making targets whose recipe is the result of an inference.
+In the first case \fB$*\fP is the target name with no suffix,
+and in the second case, is the value of the matched % pattern from
+the associated %-rule.
+\fB$^\fP expands to the set of out of date prerequisites taken from the
+current value of \fB$<\fP.
+In addition to these,
+\fB$$\fP expands to $, \fB{{\fP expands to {, \fB}}\fP expands to }, and the
+strings \fB<+\fP and \fB+>\fP are recognized
+as respectively starting and terminating a text diversion when they appear
+literally together in the same input line.
+.PP
+The difference between $? and $^ can best be illustrated by an example,
+consider:
+.RS

+.nf

+.SH "CONDITIONAL MACROS"
+.B dmake
+supports conditional macros.  These allow the definition of target specific
+macro values.  You can now say the following:
+.RS
+.sp
+\fBtarget\fP ?= \fIMacroName MacroOp Value\fP
+.sp
+.RE
+This creates a definition for \fIMacroName\fP whose value is \fIValue\fP
+only when \fBtarget\fP is being made.  You may use a conditional macro
+assignment anywhere that a regular macro assignment may appear, including
+as the value of a $(assign ...) macro.
+.LP
+The new definition is associated with the most recent cell definition
+for \fBtarget\fP.  If no prior definition exists then one is created.  The
+implications of this are immediately evident in the following example:
+.sp
+.RS
+.nf
+foo := hello
+.sp
+all : cond;@echo "all done, foo=[$(foo)] bar=[$(bar)]"
+.sp
+cond ?= bar := global decl
+.sp
+cond .SETDIR=unix::;@echo $(foo) $(bar)
+cond ?= foo := hi
+.sp
+cond .SETDIR=msdos::;@echo $(foo) $(bar)
+	cond ?= foo := hihi
+.fi
+.RE
+.sp
+The first conditional assignment creates a binding for 'bar' that is
+activated when 'cond' is made.  The bindings following the :: definitions are
+activated when their respective recipe rules are used.  Thus the
+first binding serves to provide a global value for 'bar' while any of the
+cond :: rules are processed, and the local bindings for 'foo' come into
+effect when their associated :: rule is processed.
+.LP
+Conditionals for targets of .UPDATEALL are all activated before the
+target group is made.  Assignments are processed in order.  Note that
+the value of a conditional macro assignment is NOT AVAILABLE until the
+associated target is made, thus the construct
+.sp
+.RS
+.nf
+mytarget ?= bar := hello
+mytarget ?= foo := $(bar)
+.fi
+.RE
+.sp
+results in $(foo) expanding to "", if you want the result to be "hello"
+you must use:
+.sp
+.RS
+.nf
+mytarget ?= bar := hello
+mytarget ?= foo  = $(bar)
+.fi
+.RE
+.sp
+Once a target is made any associated conditional macros are deactivated
+and their values are no longer available.  Activation occurrs after all
+inference, and .SETDIR directives have been processed and after $@ is
+assigned, but before prerequisites are processed; thereby making the values of
+conditional macro definitions available during construction of prerequisites.
+.LP
+If a %-meta rule target has associated conditional macro assignments,
+and the rule is chosen by the inference algorithm then the conditional
+macro assignments are inferred together with the associated recipe.
+.SH "DYNAMIC PREREQUISITES"
+.B dmake
+looks for prerequisites whose names contain macro expansions during target
+processing.  Any such prerequisites are expanded and the result of the
+expansion is used as the prerequisite name.  As an example the line:
+.sp
+\tfred : $$@.c
+.sp
+causes the $$@ to be expanded when \fBdmake\fP is making fred, and it resolves
+to the target \fIfred\fP.
+This enables dynamic prerequisites to be generated.  The value
+of @ may be modified by any of the valid macro modifiers.  So you can say for
+example:
+.sp
+\tfred.out : $$(@:b).c
+.sp
+where the $$(@:b) expands to \fIfred\fP.
+Note the use of $$ instead of $ to indicate the dynamic expansion, this
+is due to the fact that the rule line is expanded when it is initially parsed,
+and $$ then returns $ which later triggers the dynamic prerequisite expansion.
+Dynamic macro expansion is performed in all user defined rules, and the special
+targets .SOURCE*, and .INCLUDEDIRS.
+.PP
+\fBNOTE:\fP The use of a \fB$\fP as part of a prerequisite or target name is
+\fBstrongly discouraged\fP as the runtime macros (like $@) are expanded when
+used in a recipe line so that the $ is interpreted as a macro identifier and
+not as a character of the filename leading to invalid runtime macros.
+In addition to this no filename normalization is done for prerequisites and
+targets that contain $ characters.
+Nevertheless it is possible to use $ in prerequisites by using $$$$ but this
+is \fBnot recommended\fP and can lead to surprising results.
+.PP
+If dynamic macro expansion results in multiple white space separated tokens
+then these are inserted into the prerequisite list inplace of the dynamic
+prerequisite.  Due to the recursive nature of macro expansion the prerequisite
+list is fully expanded even if the dynamic prerequisite contained other
+runtime macros.
+.SH "BINDING TARGETS"
+This operation takes a target name and binds it to an existing file, if
+possible.
+.B dmake
+makes a distinction between the internal target name of a target and its
+associated external file name.
+Thus it is possible for a target's internal name and its external
+file name to differ.
+To perform the binding, the following set of rules is used.
+Assume that we are
+trying to bind a target whose name is of the form \fIX.suff\fP,
+where \fI.suff\fP is the suffix and \fIX\fP is the stem portion
+(ie. that part which contains the directory and the basename).
+.B dmake
+takes this target name and performs a series of search operations that try to
+find a suitably named file in the external file system.
+The search operation is user controlled
+via the settings of the various .SOURCE targets.
+.RS
+.IP 1.
+If target has the .SYMBOL attribute set then look for it in the library.
+If found, replace the target name with the library member name and continue
+with step 2.  If the name is not found then return.
+.IP 2.
+Extract the suffix portion (that following the `.') of the target name.
+If the suffix is not null, look up the special target .SOURCE.<suff>
+(<suff> is the suffix).  
+If the special target exists then search each directory given in
+the .SOURCE.<suff> prerequisite list for the target.
+If the target's suffix was null (ie. \fI.suff\fP was empty) then 
+perform the above search but use the special target .SOURCE.NULL instead.
+If at any point a match is found then terminate the search.
+If a directory in the prerequisite list is the special name `.NULL ' perform
+a search for the full target name without prepending any directory portion
+(ie. prepend the NULL directory).
+.IP 3.
+The search in step 2. failed.  Repeat the same search but this time
+use the special target .SOURCE.
+(a default target of '.SOURCE : .NULL' is defined by \fBdmake\fP at startup,
+and is user redefinable)
+.IP 4.
+The search in step 3. failed.
+If the target has the library member attribute (.LIBMEMBER)
+set then try to find the target in the library which was passed along
+with the .LIBMEMBER attribute (see the MAKING LIBRARIES section).
+The bound file name assigned to a target which is successfully
+located in a library is the same name that would be assigned had the search
+failed (see 5.).
+.IP 5.
+The search failed.  Either the target was not found in any of the search
+directories or no applicable .SOURCE special targets exist.
+If applicable .SOURCE special targets exist, but the target was not found,
+then \fBdmake\fP assigns the first name searched as the bound file name.
+If no applicable .SOURCE special targets exist,
+then the full original target name becomes the bound file name.
+.RE
+.PP
+There is potential here for a lot of search operations.  The trick is to
+define .SOURCE.x special targets with short search lists and leave .SOURCE
+as short as possible.
+The search algorithm has the following useful side effect.
+When a target having the .LIBMEMBER (library member) attribute is searched for,
+it is first searched for as an ordinary file.
+When a number of library members require updating it is desirable to compile
+all of them first and to update the library at the end in a single operation.
+If one of the members does not compile and \fBdmake\fP stops, then
+the user may fix the error and make again.  \fBdmake\fP will not remake any
+of the targets whose object files have already been generated as long as
+none of their prerequisite files have been modified as a result of the fix.
+.PP
+When \fBdmake\fP constructs target (and prerequisite) pathnames they are
+normalized  to the shortest (or most natural, see below for the cygwin case)
+representation.  Substrings like './' or of the form 'baz/..' are removed
+and multiple slashes are collapsed to one unless they are at the beginning
+of the pathname. Leading slashes are normalized according to POSIX rules,
+i.e. more than two leading slashes are reduced to one slash and a
+leading '//' is kept as it might have a special meaning. 
+For example "./foo", "bar/../foo" and foo are recognized as the same file.
+This may result in somewhat unexpected values of the macro expansion
+of runtime macros like \fB$@\fP, but is infact the corect result.
+.PP
+\fBNOTE:\fP  A cygwin \fBdmake\fP executable will accept DOS like pathnames
+with drive letters and cygwin POSIX pathnames and normalize them into its
+natural POSIX representation.  This might result in even more surprising
+values of runtime macros.

+\fBdmake\fP correctly handles the UNIX Make variable VPATH.  By definition VPATH

+.sp
+\&.SOURCE :^ $(VPATH:s/:/ /)
+.sp
+.RE
+Which takes the value of VPATH and sets .SOURCE to the same set of directories
+as specified in VPATH.
+.SH "PERCENT(%) RULES AND MAKING INFERENCES"
+When \fBdmake\fP makes a target, the target's set of prerequisites (if any)
+must exist and the target must have a recipe which \fBdmake\fP
+can use to make it.
+If the makefile does not specify an explicit recipe for the target then
+.B dmake
+uses special rules to try to infer a recipe which it can use
+to make the target.  Previous versions of Make perform this task by using
+rules that are defined by targets of the form .<suffix>.<suffix> (this is still
+supported, see "AUGMAKE META RULES") or by using the \fBnot supported\fP by
+dmake .SUFFIXES list of suffixes (see "SPECIAL TARGETS" for more details
+about .SUFFIXES).  The exact workings of this mechanism
+were sometimes difficult to understand and often limiting in their usefulness.
+Instead, \fBdmake\fP supports the concept of \fI%-meta\fP rules.  
+The syntax and semantics of these rules differ from standard rule lines as
+follows:
+.sp
+.nf
+.RS
+\fI<%-targets>\fP [\fI<attributes>\fP] \fI<ruleop>\fP [\fI<%-prereqs>\fP] [;\fI<recipe>\fP]

+If more than one %-target is present this line is equivalent to a repetition

+.PP
+The
+.I %-target
+defines a pattern against which a target whose recipe is
+being inferred gets matched.  The pattern match goes as follows:  all chars are
+matched exactly from left to right up to but not including the % sign in the
+pattern, % then matches the longest string from the actual target name
+not ending in
+the suffix given after the % sign in the pattern.
+Consider the following examples:
+.RS
+.sp
+.nf
+.Is "dir/%.c   "
+.Ii "%.c"
+matches fred.c but not joe.c.Z
+.Ii "dir/%.c"
+matches dir/fred.c but not dd/fred.c
+.Ii "fred/%"
+matches fred/joe.c but not f/joe.c
+.Ii "%"
+matches anything
+.fi
+.sp
+.RE
+In each case the part of the target name that matched the % sign is retained
+and is substituted for any % signs in the prerequisite list of the %-meta rule
+when the rule is selected during inference and
+.B dmake
+constructs the new dependency.
+.PP
+.B Please note,
+that only the first, non-indirect, prerequisite of the list is used for the
+inference mechanism. If more than one non-indirect prerequisite is given
+a warning is issued and all but the first non-indirect prerequisites are
+ignored. See below for a description of indirect prerequisites.
+.PP
+As an example the following %-meta rules describe the following:
+.RS
+.sp
+%.c : %.y ; recipe...
+.sp
+.RE
+describes how to make any file ending in .c if a corresponding file ending
+in .y can be found.
+.RS
+.sp
+foo%.o : fee%.k ; recipe...
+.sp
+.RE
+is used to describe how to make fooxxxx.o from feexxxx.k.
+.RS
+.sp
+%.a :; recipe...
+.sp
+.RE
+describes how to make a file whose suffix is .a without inferring any
+prerequisites.
+.RS
+.sp
+%.c : %.y 'yaccsrc/%.y' ; recipe...
+.sp
+.RE
+matches the corresponding .y file as prerequisite and additionally another .y
+file in the yaccsrc subdirectory as indirect prerequisite.
+Another interesting example is:
+.RS
+.sp
+% : RCS/%,v ; co $<
+.sp
+.RE
+which describes how to take any target and check it out of
+the RCS directory if the corresponding file exists in the RCS directory.
+The equivalent SCCS rule would be:
+.RS
+.sp
+% : s.% ; get $<
+.sp
+.RE
+.PP
+The previous RCS example defines an infinite rule, because it says how to make
+.I anything
+from RCS/%,v, and
+.I anything
+also includes RCS/fred.c,v.
+To limit the size of the graph that results from such rules
+.B dmake
+uses the macro variable PREP (stands for % repetition).  By default the value
+of this variable is 0, which says that no repetitions of a %-rule are to be
+generated.  If it is set to something greater than 0, then that many
+repetitions of any infinite %-rule are allowed.  If in the above
+example PREP was set to 1, then \fBdmake\fP would generate the dependency
+graph:
+.RS
+.sp
+% --> RCS/%,v --> RCS/RCS/%,v,v
+.sp
+.RE
+Where each link is assigned the same recipe as the first link.
+PREP should be used only in special cases, since it may result in
+a large increase in the number of possible prerequisites tested.
+.B dmake
+further assumes that any target that has no suffix can be made from
+a prerequisite that has at least one suffix.
+.PP
+.B dmake
+supports dynamic prerequisite generation for prerequisites of %-meta rules.
+This is best illustrated by an example.  The RCS rule shown above can infer
+how to check out a file from a corresponding RCS file only if the target
+is a simple file name with no directory information.  That is, the above rule
+can infer how to find \fIRCS/fred.c,v\fP from the target \fIfred.c\fP,
+but cannot infer how to find \fIsrcdir/RCS/fred.c,v\fP from \fIsrcdir/fred.c\fP
+because the above rule will cause \fBdmake\fP to look for RCS/srcdir/fred.c,v;
+which does not exist (assume that srcdir has its own RCS directory as is the
+common case).
+.PP
+A more versatile formulation of the above RCS check out rule is the following:
+.RS
+.sp
+% :  $$(@:d)RCS/$$(@:f),v : co $@
+.sp
+.RE
+This rule uses the dynamic macro $@ to specify the prerequisite to try to
+infer.  During inference of this rule the macro $@ is set to the value of
+the target of the %-meta rule and the appropriate prerequisite is generated by
+extracting the directory portion of the target name (if any), appending the
+string \fIRCS/\fP to it, and appending the target file name with a trailing
+\fI,v\fP attached to the previous result.
+.PP
+.B dmake
+can also infer indirect prerequisites.
+An inferred target can have a list of prerequisites added that will not
+show up in the value of $< but will show up in the value of $? and $&.
+Indirect prerequisites are specified in an inference rule by quoting the
+prerequisite with single quotes.  For example, if you had the explicit
+dependency:
+.RS
+.sp
+.nf
+fred.o : fred.c ; rule to make fred.o
+fred.o : local.h
+.fi
+.sp
+.RE
+then this can be inferred for fred.o from the following inference rule:
+.RS
+.sp
+%.o : %.c 'local.h' ; makes a .o from a .c
+.sp
+.RE
+You may infer indirect prerequisites that are a function of the value of '%'
+in the current rule.  The meta-rule:
+.RS
+.sp
+%.o : %.c '$(INC)/%.h' ; rule to make a .o from a .c
+.sp
+.RE
+infers an indirect prerequisite found in the INC directory whose name is the
+same as the expansion of $(INC), and the prerequisite name depends on the
+base name of the current target.
+The set of indirect prerequisites is attached to the meta rule in which they
+are specified and are inferred only if the rule is used to infer a recipe
+for a target.  They do not play an active role in driving the inference
+algorithm.
+The construct:
+.RS
+.sp
+%.o :| %.c %.f 'local.h'; recipe
+.sp

+%.o : %.c 'local.h' ; recipe

+.PP
+If any of the attributes .EPILOG, .IGNORE, .LIBRARY, .NOSTATE, .PHONY, .PRECIOUS,
+\&.PROLOG, .SETDIR, .SILENT, .SWAP, .USESHELL and .WINPATH

+as the result of an inference, the target's set of attributes is augmented by
+the attributes from the above set that are specified in the bound %-rule.
+Other attributes specified for %-meta rules are not inherited by the target.
+The .SETDIR attribute is treated in a special way.
+If the target already had a .SETDIR attribute set then
+.B dmake
+changes to that directory prior to performing the inference.
+During inference any .SETDIR attributes for the inferred prerequisite
+are honored.

+inference path.  If the directories do not exist no error message is issued,
+instead the corresponding path in the inference graph is rejected.
+.PP
+.B dmake
+bases all of its inferences on the inference graph constructed from the
+%-rules defined in the makefile.
+It knows exactly which targets can be made from which prerequisites by
+making queries on the inference graph.
+.PP
+For a %-meta rule to be inferred as the
+rule whose recipe will be used to make a target, the target's name must match
+the %-target pattern, and any inferred %-prerequisite must already exist or
+have an explicit recipe so that the prerequisite can be made.
+Without \fItransitive closure\fP on the inference graph the above rule
+describes precisely when an inference match terminates the search.
+If transitive closure is enabled (the usual case), and a prerequisite does
+not exist or cannot be made, then
+.B dmake
+invokes the inference algorithm recursively on the prerequisite to see if
+there is some way the prerequisite can be manufactured.  For, if the
+prerequisite can be made then the current target can also be made using the
+current %-meta rule.
+This means that there is no longer a need to give a rule
+for making a .o from a .y if you have already given a rule for making a .o
+from a .c and a .c from a .y.  In such cases
+.B dmake
+can infer how to make the
+\&.o from the .y via the intermediary .c and will remove the .c when the .o is
+made.  Transitive closure can be disabled by giving the \-T switch on the
+command line.
+.PP
+A word of caution.
+.B dmake
+bases its transitive closure on the %-meta rule targets.
+When it performs transitive closure it infers how to make a target from a
+prerequisite by performing a pattern match as if the potential prerequisite
+were a new target.
+The set of rules:

+%.o : %.c ; rule for making .o from .c
+%.c : %.y ; rule for making .c from .y
+% : RCS/%,v ; check out of RCS file
+.fi

+.RE
+will, by performing transitive closure, allow \fBdmake\fP to infer how to make
+a .o from a .y using a .c as an intermediate temporary file.  Additionally
+it will be able to infer how to make a .y from an RCS file, as long as that
+RCS file is in the RCS directory and has a name which ends in .y,v.
+The transitivity computation is performed dynamically for each target that
+does not have a recipe.  This has potential to be costly if the %-meta
+rules are not carefully specified.  The .NOINFER attribute is used to mark
+a %-meta node as being a final target during inference.  Any node with this
+attribute set will not be used for subsequent inferences.  As an example
+the node RCS/%,v is marked as a final node since we know that if the RCS file
+does not exist there likely is no other way to make it.  Thus the standard
+startup makefile contains an entry similar to:
+.RS
+.nf
+\&.NOINFER : RCS/%,v
+.fi
+.RE
+Thereby indicating that the RCS file is the end of the inference chain.
+Whenever the inference algorithm determines that a target can be made from
+more than one prerequisite and the inference chains for the two methods
+are the same length the algorithm reports an ambiguity and prints the
+ambiguous inference chains.
+.PP
+.B dmake
+tries to
+remove intermediate files resulting from transitive closure if the file

+.RE
+.SH "MAKING TARGETS"
+In order to update a target \fBdmake\fP must execute a recipe.
+When a recipe needs to be executed it is first expanded so that any macros
+in the recipe text are expanded, and it is then either executed directly or
+passed to a shell.
+.B dmake
+supports two types of recipes.  The regular recipes and group recipes.
+.PP
+When a regular recipe is invoked \fBdmake\fP executes each line of the recipe
+separately using a new copy of a shell if a shell is required.
+Thus effects of commands do not generally persist across recipe lines
+(e.g. cd requests in a recipe line do not carry over to the next recipe line).
+This is true even in environments such as \fBMSDOS\fP, where dmake internally
+sets the current working director to match the directory it was in before
+the command was executed.
+.PP
+The decision on whether a shell is required to execute a command is based on
+the value of the macro SHELLMETAS or on the specification of '+' or .USESHELL
+for the current recipe or target respectively.
+If any character in the value of
+SHELLMETAS is found in the expanded recipe text-line or the use of a shell
+is requested explicitly via '+' or .USESHELL then the command is
+executed using a shell, otherwise the command is executed directly.
+The shell that is used for execution is given by the value of the macro SHELL.
+The flags that are passed to the shell are given by the value of SHELLFLAGS.
+Thus \fBdmake\fP constructs the command line:
+.sp
+\t$(SHELL) $(SHELLFLAGS) $(expanded_recipe_command)
+.sp
+If the $(SHELLCMDQUOTE) macro is set its value is inserted before and after
+the $(expanded_recipe_command) string.
+.sp
+Normally
+.B dmake
+writes the command line that it is about to invoke to standard output.
+If the .SILENT attribute is set for the target or for
+the recipe line (via @), then the recipe line is not echoed.
+.PP
+Group recipe processing is similar to that of regular recipes, except that
+a shell is always invoked.  The shell that is invoked is given by the value of
+the macro GROUPSHELL, and its flags are taken from the value of the macro
+GROUPFLAGS.  If a target has the .PROLOG attribute set then
+.B dmake
+prepends to the shell script the recipe associated with the special target
+\&.GROUPPROLOG, and if the attribute .EPILOG is set as well, then the recipe
+associated with the special target .GROUPEPILOG is appended to the script
+file.
+This facility can be used to always prepend a common header and common trailer
+to group recipes.
+Group recipes are echoed to standard output just like standard recipes, but
+are enclosed by lines beginning with [ and ].
+.PP
+The recipe flags [+,\-,%,@] are recognized at the start of a recipe line
+even if they appear in a macro.  For example:
+.RS
+.sp
+.nf
+SH = +
+all:
+\t$(SH)echo hi
+.fi
+.sp
+.RE
+is completely equivalent to writing
+.RS
+.sp
+.nf
+SH = +
+all:
+\t+echo hi
+.fi
+.sp
+.RE
+.PP
+The last step performed by
+.B dmake
+prior to running a recipe is to set the macro CMNDNAME to the name of the
+command to execute (determined by finding the first white\-space ending token
+in the command line).  It then sets the macro CMNDARGS to be the remainder
+of the line.
+.B dmake
+then expands the macro COMMAND which by default is set to
+.RS
+.sp
+COMMAND = $(CMNDNAME) $(CMNDARGS)
+.sp
+.RE
+The result of this final expansion is the command that will be executed.
+The reason for this expansion is to allow for a different interface to
+the argument passing facilities (esp. under DOS) than that provided by
+.B dmake\fR.\fP
+You can for example define COMMAND to be
+.RS
+.sp
+COMMAND = $(CMNDNAME) @$(mktmp $(CMNDARGS))
+.sp
+.RE
+which dumps the arguments into a temporary file and runs the command
+.RS
+.sp
+$(CMNDNAME) @/tmp/ASAD23043
+.sp
+.RE
+which has a much shorter argument list.  It is now up to the command to
+use the supplied argument as the source for all other arguments.
+As an optimization, if COMMAND is not defined
+.B dmake
+does not perform the above expansion.  On systems, such as UNIX, that
+handle long command lines this provides a slight saving in processing the
+makefiles.
+.SH "MAKING LIBRARIES"
+Libraries are easy to maintain using \fBdmake\fP.  A library is a file
+containing a collection of object files.
+Thus to make a library you simply specify it as a target with the .LIBRARY
+attribute set and specify its list of prerequisites.  The prerequisites should
+be the object members that are to go into the library.  When
+.B dmake
+makes the library target it uses the .LIBRARY attribute to pass to the
+prerequisites the .LIBMEMBER attribute and the name of the library.  This
+enables the file binding mechanism to look for the member in the library if an
+appropriate object file cannot be found. 
+.B dmake
+now supports \fBElf\fP libraries on systems that support \fBElf\fP and
+hence supports, on those systems, long member file names.
+A small example best illustrates this.
+.RS
+.nf
+.sp
+mylib.a .LIBRARY : mem1.o mem2.o mem3.o
+\trules for making library...
+\t# remember to remove .o's when lib is made
+.sp
+# equivalent to:  '%.o : %.c ; ...'
+\&.c.o :; rules for making .o from .c say
+.sp
+.fi
+.RE
+.B dmake
+will use the .c.o rule for making the library members if appropriate .c files
+can be found using the search rules.  NOTE:  this is not specific in any way
+to C programs, they are simply used as an example.
+.PP
+.B dmake
+tries to handle the old library construct format in a sensible way.
+The construct 
+.I lib(member.o)
+is separated and the \fIlib\fP portion is declared
+as a library target.
+The new target is defined
+with the .LIBRARY attribute set and the \fImember.o\fP portion of the
+construct is
+declared as a prerequisite of the lib target.
+If the construct \fIlib(member.o)\fP
+appears as a prerequisite of a target in the
+makefile, that target has the new name of the lib assigned as its
+prerequisite.  Thus the following example:
+.RS
+.sp
+.nf
+a.out : ml.a(a.o) ml.a(b.o); $(CC) \-o $@  $<
+
+\&.c.o :; $(CC) \-c $(CFLAGS) \-o $@  $<
+%.a:
+.RS
+ar rv $@ $?
+ranlib $@
+rm \-rf $?
+.RE
+.sp
+.fi
+.RE
+constructs the following dependency
+graph.
+.RS
+.sp
+.nf
+a.out : ml.a; $(CC) \-o $@  $<
+ml.a .LIBRARY : a.o b.o
+
+%.o : %.c ; $(CC) -c $(CFLAGS) \-o $@  $<
+%.a :
+.RS
+ar rv $@ $?
+ranlib $@
+rm -rf $?
+.RE
+.sp
+.fi
+.RE
+and making a.out then works as expected.
+.PP
+The same thing happens for any target of the form \fIlib((entry))\fP.
+These targets have an
+additional feature in that the \fIentry\fP target has the .SYMBOL attribute
+set automatically.
+.PP
+NOTE:  If the notion of entry points is supported by the archive and by
+\fBdmake\fP (currently not the case) then
+.B dmake
+will search the archive for the entry point and return not only the
+modification time of the member which defines the entry but also the name of
+the member file.  This name will then replace \fIentry\fP and will be used for
+making the member file.  Once bound to an archive member the .SYMBOL
+attribute is removed from the target.
+This feature is presently disabled as there is little standardization
+among archive formats, and we have yet to find a makefile utilizing this
+feature (possibly due to the fact that it is unimplemented in most versions
+of UNIX Make).
+.PP
+Finally, when
+.B dmake
+looks for a library member it must first locate the library file.
+It does so by first looking for the library relative to the current directory
+and if it is not found it then looks relative to the current value of
+$(TMD).  This allows commonly used libraries to be kept near the root of
+a source tree and to be easily found by
+.B dmake\fR.\fP
+.SH "KEEP STATE"
+.B dmake
+supports the keeping of state information for targets that it makes whenever
+the macro .KEEP_STATE is assigned a value.  The value of the macro should be
+the name of a state file that will contain the state information.  If state
+keeping is enabled then each target that does not poses the .NOSTATE
+attribute will have a record written into the state file indicating the
+target's name, the current directory, the command used to update the target,
+and which, if any, :: rule is being used.  When you make this target again
+if any of this information does not match the previous settings and the
+target is not out dated it will still be re\-made.  The assumption is that one
+of the conditions above has changed and that we wish to remake the target.
+For example,
+state keeping is used in the maintenance of
+.B dmake
+to test compile different versions of the source using different compilers.
+Changing the compiler causes the compilation flags to be modified and hence
+all sources to be recompiled.
+.PP
+The state file is an ascii file and is portable, however it is
+not in human readable form as the entries represent hash keys of the above
+information.
+.PP
+The Sun Microsystem's Make construct
+.RS
+.sp
+\&.KEEP_STATE :
+.sp
+.RE
+is recognized and is mapped to \fB.KEEP_STATE:=_state.mk\fP.
+The
+.B dmake
+version of state keeping does not include scanning C source files for
+dependencies like Sun Make.  This is specific to C programs and it was
+felt that it does not belong in make.
+.B dmake
+instead provides the tool, \fBcdepend\fP, to scan C source files and to produce
+depedency information.  Users are free to modify cdepend to produce other
+dependency files.  (NOTE:
+.B cdepend
+does not come with the distribution at this time, but will be available in
+a patch in the near future)
+.SH "MULTI PROCESSING"
+If the architecture supports it then \fBdmake\fP is capable of making a target's
+prerequisites in parallel.  \fBdmake\fP will make as much in parallel as it
+can and use a number of child processes up to the maximum specified by
+MAXPROCESS or by the value supplied to the \-P command line flag.
+A parallel make is enabled by setting the value of MAXPROCESS (either directly
+or via \-P option) to a value which is > 1.
+\fBdmake\fP guarantees that all dependencies as specified in the makefile are
+honored.  A target will not be made until all of its prerequisites have been
+made.  Note that when you specify \fB-P 4\fP then four child processes are
+run concurrently but \fBdmake\fP actually displays the fifth command it will
+run immediately upon a child process becomming free.  This is an artifact of
+the method used to traverse the dependency graph and cannot be removed.
+If a parallel make is being performed then the following restrictions on
+parallelism are enforced.
+.RS
+.IP 1.
+Individual recipe lines in a non-group recipe are performed sequentially in
+the order in which they are specified within the makefile and in parallel with
+the recipes of other targets.
+.IP 2.
+If a target contains multiple recipe definitions (cf. :: rules) then these are
+performed sequentially in the order in which the :: rules are specified within
+the makefile and in parallel with the recipes of other targets.
+.IP 3.
+If a target rule contains the `!' modifier, then the recipe is performed
+sequentially for the list of outdated prerequisites and in parallel with the recipes of other targets.
+.IP 4.
+If a target has the .SEQUENTIAL attribute set then all of its prerequisites
+are made sequentially relative to one another (as if MAXPROCESS=1), but in
+parallel with other targets in the makefile.
+.RE
+.PP
+Note:  If you specify a parallel make then
+the order of target update and the order in which the associated recipes are
+invoked will not correspond to that displayed by the \-n flag.
+.SH "CONDITIONALS"
+.B dmake
+supports a makefile construct called a \fIconditional\fR.  It allows
+the user
+to conditionally select portions of makefile text for input processing
+and to discard other portions.  This becomes useful for
+writing makefiles that are intended to function for more than one target
+host and environment.  The conditional expression is specified as follows:
+.sp
+.RS
+.nf
+\&.IF  \fIexpression\fR
+   ... if text ...
+\&.ELIF  \fIexpression\fR
+   ... if text ...
+\&.ELSE
+   ... else text ...
+\&.END
+.RE
+.fi
+.sp
+The .ELSE and .ELIF portions are optional, and the conditionals may be
+nested (ie.  the text may contain another conditional).
+\&.IF, .ELSE, and .END
+may appear anywhere in the makefile, but a single conditional expression
+may not span multiple makefiles.
+.PP
+\fIexpression\fR can be one of the following forms:
+.sp
+String evaluation
+.br
+\t<text> | <text> == <text> | <text> != <text>
+.sp
+Numeric evaluation
+.br
+\t<text> <= <text> | <text> >= <text>
+.sp
+Boolean evaluation
+.br
+\t( <text> ) | <text> || <text> | <text> && <text>
+.sp
+where \fItext\fR is either text or a macro expression.  In any case,
+before the comparison is made, the expression is expanded.  The text
+portions are then selected and compared.  In the case of the numeric
+comparisons enclosing quotes are removed after expanding the expressions
+and the leading numerical parts are converted to an integer number. If no
+numerical part is found this results to 0 (zero). The
+string "12ab" for example evaluates to the number 12.
+Expressions can be nested with () and the use of || or &&.
+White space at the start and
+end of the text portion is discarded before the comparison.  This means
+that a macro that evaluates to nothing but white space is considered a
+NULL value for the purpose of the comparison.
+In the first case the expression evaluates TRUE if the text is not NULL
+otherwise it evaluates FALSE.  The remaining two cases both evaluate the
+expression on the basis of a string comparison.
+If a macro expression needs to be equated to a NULL string then compare it to
+the value of the macro $(NULL).
+You can use the $(shell ...) macro to construct more complex test expressions.

+In the previous

+respect to prgm.
+These dependencies can be stated more concisely
+by using the inference rules defined in the standard startup file.
+The default rule for making .o's from .c's looks something like this:
+.sp
+\&\t%.o : %.c; cc \-c $(CFLAGS) \-o $@ $<
+.sp
+Since there exists a rule (defined in the startup file)
+for making .o's from .c's
+\fBdmake\fR will use that rule
+for manufacturing a .o from a .c and we can specify our dependencies

+.SH "COMPATIBILITY"
+There are two notable differences between 
+.B \fBdmake\fR
+and the standard version of BSD UNIX 4.2/4.3 Make.
+.RS
+.IP 1. .3i
+BSD UNIX 4.2/4.3 Make supports wild card filename expansion for
+prerequisite names.  Thus if a directory contains a.h, b.h and c.h, then a
+line like
+.sp
+\ttarget: *.h
+.sp
+will cause UNIX make to expand the *.h into "a.h b.h c.h".  \fBdmake\fR
+does not support this type of filename expansion.
+.IP 2. .3i
+Unlike UNIX make, touching a library member causes \fBdmake\fR
+to search the library for the member name and to update the library time stamp.
+This is only implemented in the UNIX version.
+MSDOS and other versions may not have librarians that keep file time stamps,
+as a result \fBdmake\fR touches the library file itself, and prints a warning.
+.RE
+.PP
+\fBdmake\fP is not compatible with GNU Make.  In particular it does not
+understand GNU Make's macro expansions that query the file system.
+.PP
+.B dmake
+is fully compatible with SYSV AUGMAKE, and supports the following AUGMAKE
+features:
+.RS
+.IP 1. .3i
+GNU Make style \fBinclude\fP, and \fBif/else/endif\fP directives are allowed
+in non-group recipes.
+Thus, the word \fBinclude\fP appearing at
+the start of a line that is not part of a gruop recipe will be mapped
+to the ".INCLUDE" directive that \fBdamke\fP uses.
+Similarly, the words \fBifeq\fP,\fBifneq\fP,\fBelif\fP,\fBelse\fP,
+and \fBendif\fP are mapped to their corresponding \fBdmake\fP equivalents.
+.IP 2. .3i
+The macro modifier expression $(macro:str=sub) is understood and is equivalent
+to the expression $(macro:s/str/sub), with the restriction that str must match
+the following regular expression:
+.sp
+\tstr[ |\et][ |\et]*
+.sp
+(ie. str only matches at the end of a token where str is a suffix and is
+terminated by a space, a tab, or end of line)
+Normally \fIsub\fP is expanded before the substitution is made, if you specify
+\-A on the command line then sub is not expanded.
+.IP 3.
+The macro % is defined to be $@ (ie. $% expands to the same value as $@).
+.IP 4.
+The AUGMAKE notion of libraries is handled correctly.
+.IP 5.
+Directories are always made if you specify \fB\-A\fP.  This is consistent
+with other UNIX versions of Make.
+.IP 6.
+Makefiles that utilize virtual targets to force making of other targets work
+as expected if AUGMAKE special target handling is enabled.  For example:
+.sp
+.nf
+\tFRC:
+\tmyprog.o : myprog.c $(FRC) ; ...
+.fi
+.sp
+Works as expected if you issue the command
+.sp
+\t'\fBdmake\fP \-A FRC=FRC'
+.sp
+but fails with a 'don't know how to make FRC'
+error message if you do not specify AUGMAKE special target handling via
+the \-A flag (or by setting AUGMAKE:=yes internally).
+.RE
+.SH "LIMITS"
+In some environments the length of an argument string is restricted.
+(e.g. MSDOS command line arguments cannot be longer than 128 bytes if you are
+using the standard command.com command interpreter as your shell,
+.B dmake
+text diversions may help in these situations.)
+.SH "PORTABILITY"
+To write makefiles that can be moved from one environment to another requires
+some forethought.  In particular you must define as macros all those things
+that may be different in the new environment.
+.B dmake
+has two facilities that help to support writing portable makefiles, recursive
+macros and conditional expressions.  The recursive macros, allow one to define
+environment configurations that allow different environments for similar types
+of operating systems.  For example the same make script can be used for SYSV and
+BSD but with different macro definitions.
+.PP
+To write a makefile that is portable between UNIX and MSDOS requires both
+features since in almost all cases you will need to define new recipes for
+making targets.  The recipes will probably be quite different since the
+capabilities of the tools on each machine are different.  Different
+macros will be needed to help handle the smaller differences in the two
+environments.
+.SH FILES
+Makefile, makefile, startup.mk (use dmake \-V to tell you where the startup
+file is)

+.SH BUGS
+Some system commands return non-zero status inappropriately.
+Use
+.B \-i
+(`\-' within the makefile) to overcome the difficulty.
+.PP
+Some systems do not have easily accessible
+time stamps for library members (MSDOS, AMIGA, etc)
+for these \fBdmake\fR uses the time stamp of the library instead and prints
+a warning the first time it does so.  This is almost always ok, except when
+multiple makefiles update a single library file.  In these instances it is
+possible to miss an update if one is not careful.
