155Usage: ${PROGRAM} [OPTION]... [FILENAME]
156Generates a header file from an XML source file.
157
158It grabs all strings between <_translatable_node> and its end tag in
159XML files. Read manpage (man ${PROGRAM}) for more info.
160
161      --type=TYPE   Specify the file type of FILENAME. Currently supports:
162                    "gettext/glade", "gettext/ini", "gettext/keys"
163                    "gettext/rfc822deb", "gettext/schemas",
164                    "gettext/scheme", "gettext/xml", "gettext/quoted"
165  -l, --local       Writes output into current working directory
166                    (conflicts with --update)
167      --update      Writes output into the same directory the source file 
168                    reside (conflicts with --local)
169      --srcdir      Root of the source tree
170  -v, --version     Output version information and exit
171  -h, --help        Display this help and exit
172  -q, --quiet       Quiet mode
173
174Report bugs to http://bugzilla.gnome.org/ (product name "$PACKAGE")
