# Exclude contrib subdir - it holds a benchmark program which has a copy of
# every theme string, causing duplicates.

# TODO: we try to obey $srcdir but it will probably fail on anything other than
# ".", as the paths that xgettext will put into the pot file will most likely
# differ from the ones listed in po/POTFILES.in. However the logic necessary to
# strip the right prefix in all possible corner case makes it too much to worry
# about in advance.
