Usage: ${PROGRAM} [OPTION]... [FILENAME]
Generates a header file from an XML source file.

It grabs all strings between <_translatable_node> and its end tag in
XML files. Read manpage (man ${PROGRAM}) for more info.

      --type=TYPE   Specify the file type of FILENAME. Currently supports:
                    "gettext/glade", "gettext/ini", "gettext/keys"
                    "gettext/rfc822deb", "gettext/schemas",
                    "gettext/scheme", "gettext/xml", "gettext/quoted"
  -l, --local       Writes output into current working directory
                    (conflicts with --update)
      --update      Writes output into the same directory the source file 
                    reside (conflicts with --local)
      --srcdir      Root of the source tree
  -v, --version     Output version information and exit
  -h, --help        Display this help and exit
  -q, --quiet       Quiet mode

Report bugs to http://bugzilla.gnome.org/ (product name "$PACKAGE")
or send email to <xml-i18n-tools\@gnome.org>.
