Ptalon requires ANTLR 2.7.7 to run properly, which should be included
as a jar file in $PTII/ptolemy/actor/ptalon/antlr. ANTLR can be found at
http://www.antlr.org
.
If you make changes to
the grammar files (files with .g) extension, you must compile them with antlr,
calling "java antlr.Tool foo.g".
