NAME

       msgmerge - merge message catalog and template

SYNOPSIS

       msgmerge [OPTION] def.po ref.pot

DESCRIPTION

       Merges two Uniforum style .po files together.  The def.po file is an existing PO file with
       translations which will be taken over to the newly created file  as  long  as  they  still
       match;  comments  will  be  preserved,  but  extracted comments and file positions will be
       discarded.  The ref.pot file is the last created PO file with up-to-date source references
       but  old  translations,  or  a  PO  Template  file  (generally  created  by xgettext); any
       translations or comments in the file will be discarded,  however  dot  comments  and  file
       positions will be preserved.  Where an exact match cannot be found, fuzzy matching is used
       to produce better results.

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

       def.po translations referring to old sources

       ref.pot
