#
# The def.po file is an existing PO file with translations which will be taken
# over to the newly created file as long as they still match; comments will be preserved,
# but extracted comments and file positions will be discarded.
#
# The ref.pot file is the last created PO file with up-to-date source references but
# old translations, or a PO Template file (generally created by rgettext);
# any translations or comments in the file will be discarded, however dot
# comments and file positions will be preserved. Where an exact match
# cannot be found, fuzzy matching is used to produce better results.
#
# Usually you don't need to call this function directly. Use GetText.update_pofiles instead.
