147Usage: ${PROGRAM} [OPTION]... [FILENAME]
148Generates a header file from an XML source file.
149

151XML files. Read manpage (man ${PROGRAM}) for more info.
152
153      --type=TYPE   Specify the file type of FILENAME. Currently supports:
154                    "gettext/glade", "gettext/ini", "gettext/keys"
155                    "gettext/rfc822deb", "gettext/schemas",
156                    "gettext/scheme", "gettext/xml"
157  -l, --local       Writes output into current working directory
158                    (conflicts with --update)
159      --update      Writes output into the same directory the source file
160                    reside (conflicts with --local)
161      --srcdir      Root of the source tree
162  -v, --version     Output version information and exit
163  -h, --help        Display this help and exit
