     xgettext - extract gettext call strings from C programs

     xgettext [-ns] [ -a [-x exclude-file]]  [-c comment-tag]  [-
     d default-domain] [-j] [-m prefix] [-M suffix] [-p pathname]
     -| filename...

     xgettext  -h

     The xgettext utility is used to  automate  the  creation  of
     portable  message files (.po). A .po file contains copies of
     "C" strings that  are  found  in   ANSI  C  source  code  in
     filename  or  the standard input if  `-' is specified on the
     command line. The  .po file can be  used  as  input  to  the
     msgfmt(1)  utility, which produces a binary form of the mes-
     sage file that can be  used by application during run-time.

     xgettext writes msgid  strings  from  gettext(3C)  calls  in
     filename to the default output file messages.po. The default
     output file name can be changed by  -d option. msgid strings
     in   dgettext()   calls  are  written  to  the  output  file
     domainname.po where domainname is the first parameter to the
     dgettext() call.

     By default, xgettext creates a   .po  file  in  the  current
     working  directory, and each entry is in the same order that
     the strings are extracted from filenames. When the -p option
     is  specified,  the   .po  file  is created in the  pathname
     directory. An existing .po file is overwritten.

     Duplicate  msgids are written to the  .po  file  as  comment
     lines.  When the  -s option is specified, the  .po is sorted
     by the msgid string, and all duplicated msgids are  removed.
     All   msgstr directives in the .po file are empty unless the
     -m option is used.

     The following options are supported:

     -n                      Add comment lines to the output file
                             indicating file name and line number
                             in  the  source  file   where   each
                             extracted   string  is  encountered.
                             These lines appear before each msgid
                             in the following format:

                             # # File: filename, line: line-number

     -s                      Generate output  sorted  by   msgids
                             with all duplicate  msgids removed.

     -a                      Extract all strings, not just  those
                             found in gettext(3C), and dgettext()
                             () calls.  Only  one   .po  file  is

     -c comment-tag          The  comment  block  beginning  with
                             comment-tag  as  the  first token of
                             the comment block is  added  to  the
                             output .po file as  # delimited com-
                             ments. For multiple  domains,  xget-
                             text  directs  comments and messages
                             to the prevailing text domain.

     -d default-domain       Rename  default  output  file   from
                             messages.po to default-domain .po.

     -j                      Join messages with existing  message
                             files.   If  a  .po  file  does  not
                             exist, it is created.  If a .po file
                             does   exist,   new   messages   are
                             appended.  Any duplicate msgids  are
                             commented  out  in the resulting .po
                             file.   Domain  directives  in   the
                             existing   .po   file  are  ignored.
                             Results not guaranteed if the exist-
                             ing message file has been edited.

     -m prefix               Fill in  the  msgstr  with   prefix.
                             This  is  useful  for debugging pur-
                             poses. To make msgstr  identical  to
                             msgid, use an empty string  ("") for

     -M suffix               Fill in  the  msgstr  with   suffix.
                             This  is  useful  for debugging pur-

     -p pathname             Specify the directory where the out-
                             put   files  will  be  placed.  This
                             option overrides the current working

     -x exclude-file         Specify a  .po file that contains  a
                             list  of  msgids  that are not to be
                             extracted from the input files.  The
                             format  of exclude-file is identical
                             to the .po file. However,  only  the
                             msgid directive line in exclude-file
                             is used. All other lines are  simply
                             ignored.   The -x option can only be
                             used with the -a option.

     xgettext is not able to extract cast  strings,  for  example
     ANSI  C  casts of literal strings to (const char *). This is
     unnecessary anyway,  since  the  prototypes  in  <libintl.h>
     already specify this type.

     In messages and translation notes, lines greater  than  2048
     characters  are  truncated  to 2048 characters and a warning
     message is printed to stderr.
