The Beaver is a LALR(1) parser generator. It takes a context free
grammar as an input and converts it into a Java class that implements
a parser for the specified language.

Beaver is similar to CUP and other LALR parser generators, yet it has
several important differences:
- it is very fast (almost 5 times faster than CUP, probably as fast as
  LALR Java parser can get due to the use of perfectly hashed action
  tables)
- it uses some EBNF notations in grammar syntax to allow more compact
  specifications
- it is implemented to allow multiple parser instances to work in
  parallel
- its instances can be reused
- it can be easily integrated in a development environment

Beaver's home is at http://beaver.sourceforge.net
