sub Console_Write_IntltoolHelp

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
