189Usage: ${PROGRAM} [OPTION]... LANGCODE
190Updates PO template files and merge them with the translations.
191
192Mode of operation (only one is allowed):
193  -p, --pot                   generate the PO template only
194  -s, --headers               generate the header files in POTFILES.in
195  -m, --maintain              search for left out files from POTFILES.in
196  -r, --report                display a status report for the module
197  -d, --dist                  merge LANGCODE.po with existing PO template
198
199Extra options:
200  -g, --gettext-package=NAME  override PO template name, useful with --pot
201  -o, --output-file=FILE      write merged translation to FILE
202  -x, --verbose               display lots of feedback
203      --help                  display this help and exit
204      --version               output version information and exit
205
206Examples of use:
207${PROGRAM} --pot    just create a new PO template
208${PROGRAM} xy       create new PO template and merge xy.po with it
209
210Report bugs to http://bugzilla.gnome.org/ (product name "$PACKAGE")
