[kepler-dev] confused about the MOML file

[Dan Higgins]

Just a slight addition to Matt's comments ---

If you have a new java-based actor (rahter than a composite), you need 
to add its class to the classpath. Then you can use the 
"Tools/Instantiate Component" to get it to display on the canvas (using 
the path to its class). Once it appears on the canvas, you can then use 
the 'Export to KAR' popup menu to automatically generate a KAR file. 
Note that you might want to try the "Semantic Type Annotation..." popup 
first to set where it appears in the actor menu. To get it to appear in 
the actor tree, you can then use the "File/Import Archive" menu
