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