Ragel State Machine Compiler

There is a new compiler tool recently released called Ragel. It is useful
for performing lexical analysis and general parsing of regular languages.

Brief description:


Ragel compiles finite state machines from regular languages into runnable
C code. It allows you to insert function calls at any point in your
regular language, and to control the non-determinism in the resulting
machines. It understands concatenation, union (the "or" operator),
kleene star, subtraction, and intersection, as well as some helpers like
"!", "?" and "+". Ragel's finite state machines are closed under all of
its operators. This property allows for arbitrary regular lanuages to
be described. It can be used to create a parser for any language that
is regular.
