6.11.1.2 Extract a Message Subset from a PO File

Nobody wants to translate the same messages again and again; thus you may wish to have a compendium file containing `getopt.c' messages.

To extract a message subset (e.g., all `getopt.c' messages) from an existing PO file into one compendium file you can use `msggrep':

msggrep --location src/getopt.c -o compendium.po file.po
