msgfilter [OPTION] FILTER [FILTER-OPTION]

       Applies a filter to all translations of a translation catalog.

       Mandatory  arguments  to  long  options are mandatory for short options

   Input file location:
       -i, --input=INPUTFILE
              input PO file

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

       If no input file is given or if it is -, standard input is read.

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

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

       The  FILTER  can  be any program that reads a translation from standard
       input and writes a modified translation to standard output.

   Useful FILTER-OPTIONs when the FILTER is 'sed':
       -e, --expression=SCRIPT
              add SCRIPT to the commands to be executed

       -f, --file=SCRIPTFILE
              add the contents of SCRIPTFILE to the commands to be executed

       -n, --quiet, --silent
              suppress automatic printing of pattern space

   Input file syntax:
       -P, --properties-input
              input file is in Java .properties syntax

              input file is in NeXTstep/GNUstep .strings syntax

   Output details:
              use colors and other text attributes always

              use colors and other text  attributes  if  WHEN.   WHEN  may  be
              'always', 'never', 'auto', or 'html'.

              indented output style

              keep header entry unmodified, don't filter it

       -w, --width=NUMBER
              set output page width

              do  not  break  long  message lines, longer than the output page
              width, into several lines

       -s, --sort-output
              generate sorted output

       -F, --sort-by-file
              sort output by file location

   Informative output:
       -h, --help
