Marcus, I'm not familiar with JLex or CUP, I have read some
articles about them and thought, it might be interesting to take a
look at them - unfortunately never found the time. 

I am quite familiar with Ant, though. If you are interested in
creating <jlex> and <cup> tasks for Ant, I'd be happy to assist with
the Ant specific part of it.

Cheers

	Sure, that would be great. What has to be done is as follows:

	Before the source is compiled, the parser and scanner have to be
	generated using JLex and CUP.

	This line generates the scanner:

		java -classpath jlex.jar JLex.Main Scanner.jlex
		mv Scanner.jlex.java Yylex.java

	and this line generates the parser:

		java -classpath cup.jar java_cup.Main < Parser.cup

	The move from Scanner.jlex.java to Yylex.java is currently required as
	Yylex is a public class. (The scanner filename could be changed to
	Yylex so that the move isn't necessary).

	Something similar needs to be added to the build.xml. How it's done is 
	completely up to you! :-)

	The cocoon build should then proceed as normal.

	If there are any problems let me know.

	Thanks again for your help. :-)

	Cheers,

	Marcus
