192Usage: ${PROGRAM} [OPTION]... LANGCODE
193Updates PO template files and merge them with the translations.
194
195Mode of operation (only one is allowed):
196 -p, --pot generate the PO template only
197 -s, --headers generate the header files in POTFILES.in
198 -m, --maintain search for left out files from POTFILES.in
199 -r, --report display a status report for the module
200 -d, --dist merge LANGCODE.po with existing PO template
201
202Extra options:
203 -g, --gettext-package=NAME override PO template name, useful with --pot
204 -o, --output-file=FILE write merged translation to FILE
205 -x, --verbose display lots of feedback
206 --help display this help and exit
207 --version output version information and exit
208
209Examples of use:
210${PROGRAM} --pot just create a new PO template
211${PROGRAM} xy create new PO template and merge xy.po with it
212
213Report bugs to http://bugzilla.gnome.org/ (product name "$PACKAGE")
214or send email to <xml-i18n-tools\@gnome.org>.
