[antlr-interest] desperate noob

[Louis Burroughs]

Just spent a week creating an esql grammar. After finally getting a decent
test run something locked up in antlrworks and I managed to delete my entire
grammar.  Yeah, yeah source control lesson learned. My generated java is now
safely tucked away.  Is there any way to go from the java output to recreate
a grammar?  I have the antlr reference book so if someone can point me to a
page number or chapter I would appreciate it.

tia,
Louis
