/usr/bin/msguniq

Usage: /usr/bin/msguniq [OPTION] [INPUTFILE]

Unifies duplicate translations in a translation catalog.
Finds duplicate translations of the same message ID.  Such duplicates are
invalid input for other programs like msgfmt, msgmerge or msgcat.  By
default, duplicates are merged together.  When using the --repeated option,
only duplicates are output, and all other messages are discarded.  Comments
and extracted comments will be cumulated, except that if --use-first is
specified, they will be taken from the first translation.  File positions
will be cumulated.  When using the --unique option, duplicates are discarded.

Mandatory arguments to long options are mandatory for short options too.
