You can find the complete grammar file and a sample of valid input here:
The grammar has changed a bit since I wrote the original message here,
but the problems remain.
I don't know how to use the debugger, and there appear to be significant
discrepancies between the ANTLRworks User's Guide
(<http://www.antlr.org/works/doc/antlrworks.pdf>) and the program as it
presents itself on my system. When I issue the "Debug..." command, I
get an alert stating "Compiler Exception: ClassNotFoundException:
com.sun.tools.javac.Main". I do have a full JDK installed, of course.
I'm using SuSE Linux 10.0 and Sun's Java 1.5.0_07.
