187Usage: ${PROGRAM} [OPTION]... LANGCODE
188Updates PO template files and merge them with the translations.
189
190Mode of operation (only one is allowed):
191  -p, --pot                   generate the PO template only
192  -s, --headers               generate the header files in POTFILES.in
193  -m, --maintain              search for left out files from POTFILES.in
194  -r, --report                display a status report for the module
195  -d, --dist                  merge LANGCODE.po with existing PO template
196
197Extra options:
198  -g, --gettext-package=NAME  override PO template name, useful with --pot
199  -o, --output-file=FILE      write merged translation to FILE
200  -x, --verbose               display lots of feedback
201      --help                  display this help and exit
202      --version               output version information and exit
203
204Examples of use:
205${PROGRAM} --pot    just create a new PO template
206${PROGRAM} xy       create new PO template and merge xy.po with it
