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.
