The Ptolemy II Expression Language is documented in Chapter 3, "Expressions" (Ptolemy Website) Local HTML Version).
The expression language uses JavaCC, which is available from
http://javacc.dev.java.net. You need only install JavaCC is you plan on extending the
syntax of the expression language by modifying the .jjt files.
$PTII/configure looks for JavaCC in $PTII/vendors/sun/javacc-3.2,
so either install JavaCC in that location or use the --with-javacc= flag
and then rerun configure.
