Usage: ${PROGRAM} [OPTION]... [FILENAME]
149
Generates a header file from an XML source file.
151
It grabs all strings between <_translatable_node> and its end tag in
152
XML files. Read manpage (man ${PROGRAM}) for more info.
154
--type=TYPE Specify the file type of FILENAME. Currently supports:
155
"gettext/glade", "gettext/ini", "gettext/keys"
156
"gettext/rfc822deb", "gettext/schemas",
157
"gettext/scheme", "gettext/xml"
158
-l, --local Writes output into current working directory
159
(conflicts with --update)
160
--update Writes output into the same directory the source file
161
reside (conflicts with --local)
162
--srcdir Root of the source tree
163
-v, --version Output version information and exit
164
-h, --help Display this help and exit
165
-q, --quiet Quiet mode
167
