## Sub for printing usage information
150
Usage: ${PROGRAM} [OPTION]... [FILENAME]
151
Generates a header file from an XML source file.
153
It grabs all strings between <_translatable_node> and its end tag in
154
XML files. Read manpage (man ${PROGRAM}) for more info.
156
--type=TYPE Specify the file type of FILENAME. Currently supports:
157
"gettext/glade", "gettext/ini", "gettext/keys"
158
"gettext/rfc822deb", "gettext/schemas",
159
"gettext/scheme", "gettext/xml"
160
-l, --local Writes output into current working directory
161
(conflicts with --update)
162
--update Writes output into the same directory the source file
163
reside (conflicts with --local)
164
--srcdir Root of the source tree
165
-v, --version Output version information and exit
166
-h, --help Display this help and exit
167
-q, --quiet Quiet mode
169
Report bugs to http://bugzilla.gnome.org/ (product name "$PACKAGE")
170
or send email to <xml-i18n-tools\@gnome.org>.
