[kepler-dev] Re: Ptolemy II 4.0.1 is available for download

[Bertram Ludaescher]

Christopher:

Are the plans to bring it back later? (I guess it was not yet ready
for "prime time" !?)

For now, I guess Kepler could "adopt the unloved orphan" in the Kepler 
cvs!?

In the mid/long run, I think it will be good to have a set of higher
order actors (as mentioned before, e.g. by Edward).
