Indeed. You can run the generator by invoking doupdate on
shell1.sourceforge.net if you want, but I'd take this as a test case
whether the mechanism still works.

Anybody advise of a mechanism that performs the update on commit is
highly appreciated. Please note that the specific problem is not to
just execute some script (such a script is in CVSROOT already), but to
have that script properly run on shell1 even though the commit occurs
on cvs.sourceforge.net.
