This is what fortress does: http://research.sun.com/projects/plrg/fortress.pdf However, if you look at the ascii version of the code, it's pretty hard to read: http://fortress.sunsource.net/source/browse/fortress/trunk/ProjectFortress/demos/ It does render nicely though: http://research.sun.com/projects/plrg/faq/NAS-CG.pdf I'm not sure yet if this is worth the cost yet though. ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
