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 ${PROGRAM}) for more info.
--type=TYPE Specify the file type of FILENAME. Currently supports:
"gettext/glade", "gettext/ini", "gettext/keys"
"gettext/rfc822deb", "gettext/schemas",
"gettext/scheme", "gettext/xml"
-l, --local Writes output into current working directory
(conflicts with --update)
--update Writes output into the same directory the source file
reside (conflicts with --local)
--srcdir Root of the source tree
-v, --version Output version information and exit
-h, --help Display this help and exit
-q, --quiet Quiet mode
Report bugs to http://bugzilla.gnome.org/ (product name "$PACKAGE")
or send email to <xml-i18n-tools\@gnome.org>.
