# docbook_expandLicenses.sh -- This function modifies the final
86e000
# DocBook instance to add license information. We are doing this way
86e000
# because using XInclude doesn't work and we want to reuse license
86e000
# information in all documents. So, if we cannot link the files, we
86e000
# modify the final instance and append the license information to it.
86e000
# Later, to reuse translation messages, the locale functionality takes
86e000
# care of merging po files related to licenses into documentation po
86e000
# file so changes made to licenses translations will also be available
86e000
# to documentation manuals in different languages.
