150Usage: ${PROGRAM} [OPTION]... [FILENAME]
151Generates a header file from an XML source file.
152
153It grabs all strings between <_translatable_node> and its end tag in
154XML files. Read manpage (man ${PROGRAM}) for more info.
155
156      --type=TYPE   Specify the file type of FILENAME. Currently supports:
157                    "gettext/glade", "gettext/ini", "gettext/keys"
158                    "gettext/rfc822deb", "gettext/schemas",
159                    "gettext/scheme", "gettext/xml"
160  -l, --local       Writes output into current working directory
161                    (conflicts with --update)
162      --update      Writes output into the same directory the source file 
163                    reside (conflicts with --local)
164      --srcdir      Root of the source tree
165  -v, --version     Output version information and exit
166  -h, --help        Display this help and exit
167  -q, --quiet       Quiet mode
168
169Report bugs to http://bugzilla.gnome.org/ (product name "$PACKAGE")
