[ragel-users] LALR(1) companion tool for Ragel scanner

[Adrian Thurston]

My own parser generator, kelbt, has a host language interface similar to 
that of ragel. It is not 1.0 tough and there are no docs yet. It is 
oriented around research problems. Eg it is backtracking bottom up and 
as such is in a less common class of parser generators.

That said, it is in debian and I use it for several of my own projects, 
including ragel.
