Hello!

Removal of cg-Xlib inclusion in *-id scripts broke "--help" switch.
When cg-Xlib is sourced indirectly through cg-Xnormid, the help text is
treated like an ID, and its last word is dropped.

Lack of USAGE string in the *-id scripts breaks the documentation
generation because empty synopsis causes invalid XML.  Thus the USAGE
strings should be provided.

Dear diary, on Mon, Sep 19, 2005 at 11:29:41PM CEST, I got a letter
where Pavel Roskin <proski@gnu.org> told me that...

do we really need --help in *-id? They are some kind of scripts
half-internal and half for the user - their _primary_ use is from the
other scripts, but they are standalone since they can be useful for the
end user as well in various situations. I can roughly remember cg-Xlib
inclusion in those scripts being significantly visible on the running
times of the users.

Thanks, this was already taken care of by Martin Atukunda.
