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