 9.6 Invoking the `msgcomm' Program
 ==================================
 
      msgcomm [OPTION] [INPUTFILE]...
 
    The `msgcomm' program finds 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 and extract comments will be
 preserved, but only from the first PO file to define them.  File
 positions from all PO files will be cumulated.
 
 9.6.1 Input file location
 -------------------------
 
 `INPUTFILE ...'
      Input files.
 
 `-f FILE'
 `--files-from=FILE'
      Read the names of the input files from FILE instead of getting
      them from the command line.
 
 `-D DIRECTORY'
 `--directory=DIRECTORY'
      Add DIRECTORY to the list of directories.  Source files are
      searched relative to this list of directories.  The resulting `.po'
      file will be written relative to the current directory, though.
 
 
    If INPUTFILE is `-', standard input is read.
 
 9.6.2 Output file location
 --------------------------
 
 `-o FILE'
 `--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 `-'.
 
 9.6.3 Message selection
 -----------------------
 
 `-< NUMBER'
 `--less-than=NUMBER'
      Print messages with less than NUMBER definitions, defaults to
      infinite if not set.
 
 `-> NUMBER'
 `--more-than=NUMBER'
      Print messages with more than NUMBER definitions, defaults to 1 if
      not set.
 
 `-u'
 `--unique'
      Shorthand for `--less-than=2'.  Requests that only unique messages
      be printed.
 
 
 9.6.4 Input file syntax
 -----------------------
 
 `-P'
 `--properties-input'
      Assume the input files are Java ResourceBundles in Java
      `.properties' syntax, not in PO file syntax.
 
 `--stringtable-input'
      Assume the input files are NeXTstep/GNUstep localized resource
      files in `.strings' syntax, not in PO file syntax.
 
 
 9.6.5 Output details
 --------------------
 
 `--force-po'
      Always write an output file even if it contains no message.
 
 `-i'
 `--indent'
      Write the .po file using indented style.
 
 `--no-location'
      Do not write `#: FILENAME:LINE' lines.
 
 `-n'
 `--add-location'
      Generate `#: FILENAME:LINE' lines (default).
 
 `--strict'
      Write out a strict Uniforum conforming PO file.  Note that this
      Uniforum format should be avoided because it doesn't support the
      GNU extensions.
 
 `-p'
 `--properties-output'
      Write out a Java ResourceBundle in Java `.properties' syntax.  Note
      that this file format doesn't support plural forms and silently
      drops obsolete messages.
 
 `--stringtable-output'
      Write out a NeXTstep/GNUstep localized resource file in `.strings'
      syntax.  Note that this file format doesn't support plural forms.
 
 `-w NUMBER'
 `--width=NUMBER'
      Set the output page width.  Long strings in the output files will
      be split across multiple lines in order to ensure that each line's
      width (= number of screen columns) is less or equal to the given
      NUMBER.
 
 `--no-wrap'
      Do not break long message lines.  Message lines whose width
      exceeds the output page width will not be split into several
      lines.  Only file reference lines which are wider than the output
      page width will be split.
 
 `-s'
 `--sort-output'
      Generate sorted output.  Note that using this option makes it much
      harder for the translator to understand each message's context.
 
 `-F'
 `--sort-by-file'
      Sort output by file location.
 
 `--omit-header'
      Don't write header with `msgid ""' entry.
 
 
 9.6.6 Informative output
 ------------------------
 
 `-h'
 `--help'
      Display this help and exit.
 
 `-V'
 `--version'
      Output version information and exit.
