[kepler-dev] build a custom actor

[Dan Higgins]

Hi dejw (and others)
    It is possible to include jar files used by an actor in the kar 
package. An example can be seen in $KEPLER/src/actors/ImageJ (This is an 
example of the ImageJ.kar file.) The key is information in the 
MANIFEST.MF  file which includes references to the jars. Unfortunately, 
I think you still need to create this package by hand.

See http://www.kepler-project.org/Wiki.jsp?page=AddingJarsToKarFiles

for a brief discussion.
