[kepler-users] Export Ptolemy actors to Kepler platform.

[Dan Higgins]

Hi,
    Whether or not you can instantiate the PythonScript actors depends 
on what version of Kepler you are working with. Up until quite recently 
(after the RC1 release), the Ptolemy PythonScript actor code was not 
included in the Kepler code base. It is now in the current head of CVS 
and I assume it will be in the 1.0 release. (I changed the ant build to 
include the PTII python code and am now working on building some python 
actor examples.)

    To include the Python actors in an older version of Kepler, you need 
to compile the PTII python code and add it to the Kepler classpath along 
with the jython.jar needed by the actor. Then you should be able to 
instantiate the actor from the Kepler menu.
