- 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>.
