## 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.
