       msgmerge - merge message catalog and template


       msgmerge [OPTION] def.po ref.pot


       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.

   Input file location:
       def.po translations referring to old sources

              references to new sources

       -D, --directory=DIRECTORY
              add DIRECTORY to list for input files search

       -C, --compendium=FILE

   Operation mode:
       -U, --update

   Output file location:
       -o, --output-file=FILE
              write output to specified file

       The results are written to standard output if no output file is specified or if it is -.

       Output file location in update mode: The result is written back to def.po.

              make a backup of def.po

              override the usual backup suffix

       The version control method may  be  selected  via  the  --backup  option  or  through  the
       VERSION_CONTROL environment variable.  Here are the values:
