# Sign dylibs
#
# Executables get signed right after linking, see
# solenv/gbuild/platform/macosx.mk. But many of our dylibs are built
# by ad-hoc or 3rd-party mechanisms, so we can't easily sign them
# right after linking. So do it here.
#
# The dylibs in the Python framework are called *.so. Go figure
#
# First sign all files that can use the default identifier in the hope
# that codesign will contact the timestamp server just once for all
# mentioned on the command line.
#
# On Mavericks also would like to have data files signed...
# add some where it makes sense. Make a depth-first search to sign the contents
# of e.g. the spotlight plugin before attempting to sign the plugin itself
