NAME

       msgcat - combines several message catalogs

SYNOPSIS

       msgcat [OPTION] [INPUTFILE]...

DESCRIPTION

       Concatenates  and merges the specified PO files.  Find messages which are common to two or
       more of the specified PO files.  By using the --more-than option, greater commonality  may
       be  requested before messages are printed.  Conversely, the --less-than option may be used
       to specify less commonality before messages are printed  (i.e.   --less-than=2  will  only
       print  the  unique  messages).   Translations,  comments,  extracted  comments,  and  file
       positions will be cumulated, except that if --use-first is specified, they will  be  taken
       from the first PO file to define them.

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