Usage: ${PROGRAM} [OPTION]... LANGCODE
195
Updates PO template files and merge them with the translations.
197
Mode of operation (only one is allowed):
198
-p, --pot generate the PO template only
199
-s, --headers generate the header files in POTFILES.in
200
-m, --maintain search for left out files from POTFILES.in
201
-r, --report display a status report for the module
202
-d, --dist merge LANGCODE.po with existing PO template
205
-g, --gettext-package=NAME override PO template name, useful with --pot
206
-o, --output-file=FILE write merged translation to FILE
207
-x, --verbose display lots of feedback
208
--help display this help and exit
209
--version output version information and exit
212
${PROGRAM} --pot just create a new PO template
213
${PROGRAM} xy create new PO template and merge xy.po with it
215
