Many thanks to all your replies.

Please see some more comments/questions intermixed below (somewhat in
the order I've tried things...)

Thanks Dan; since I do have JAI, I just changed build-ptolemy.xml accordingly
and the JAI-based actors got compiled (perhaps a build.properties would help
for some customization). However, they still don't show up in the browser
menu, so ...

... how can they be annotated?

This a highly desirable feature (startup time should be significantly

As a general comment, some users would like to customize their ptolemy/kepler
environments in a way that only those packages they're interested in get
loaded (or at least to discard some heavy ones they don't depend on). I think
that would speed up development and tests. Is there currently an established
procedure to obtain a desired configuration in this sense?
Perhaps, the KSW mechanism will properly fulfill this request anyway, so the
question is: when will the KSW be usable?

Thanks again,
