SYNOPSIS

DESCRIPTION
    Extracts  all messages of a translation catalog that match a given pat-
    tern or belong to some given source files.

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

  Input file location:

    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 -.

  Message selection:
    [-N SOURCEFILE]... [-M DOMAINNAME]...  [-K MSGID-PATTERN] [-T
    MSGSTR-PATTERN] [-C COMMENT-PATTERN]

    A message is selected  if it comes from one of the specified source
    files, or if it comes from one of the specified domains, or if -K is
    given and its key (msgid or msgid_plural) matches MSGID-PATTERN, or if
    -T is given and its translation (msgstr) matches MSGSTR-PATTERN, or if
    -C is given and the translator's comment matches COMMENT-PATTERN.

    When more than  one selection  criterion is specified, the set of
    selected messages is the union of the selected messages of each crite-
    rion.

  MSGID-PATTERN or MSGSTR-PATTERN syntax:
    [-E | -F] [-e PATTERN | -f FILE]...

    expressions if -E is given, or fixed strings if -F is given.
