 # Helper function for extracting translatable messages from Calligra source code.
 # Usage: kundo2_aware_xgettext <pot-filename-without-path> <source-files-list>
 # If there are no messages or the <source-files-list> is empty, the pot file is deleted.
 #
 # Example usage that creates $podir/myapp.pot file:
 #     kundo2_aware_xgettext myapp.pot `find . -name \*.cpp -o -name \*.h`
 #
 function kundo2_aware_xgettext() {

         # we rely on last line being a 'msgstr' signaling that strings has been extracted (a header is always present)
         # normally it ends with 'msgstr ""' but if plural it can end with eg 'msgstr[1] ""'

 # How to unit test:
 #   export podir=.
 #   cp init-sample.pot sample.pot
 #   source krita_xgettext.sh
 #   add_ctxt_qtundo sample.pot
 #
 #   Then check that all messages in sample.pot have "(qtundo-format)" in msgctxt.
