## NAME
       msguniq - unify duplicate translations in message catalog

## SYNOPSIS
       **msguniq** [_OPTION_] [_INPUTFILE_]

## DESCRIPTION
       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.
