# Convert localized XHP files and TREE files to HTML.
#
# Syntax: convert2html tarball productversion source
#
# Example
# ./convert2html.sh buildtargets_5403.tar.gz 5.4 libreoffice-help-5.4.0.3.tar.xz
#
# This script convert localized XHP and TREE files available as tarballs into
# a set of html pages.
#
# Conversion is done by listing the available languages in the tarball and
# execting the XSLT transformations on each XHP and tree files.
#
# Note: tarball, source and productversion must match.
#
# Special case for converting en-US XHP files to HTML. The en-US source is
# taken from the published helpcontent2 source tarball.
#
# companion files are moved to the right position in the html folder
# Media files are added too.
