[ANN] Ruth 0.8.0

The latest version of Robert Feldt's Ruth (version 0.8.0) is now available
from the RubyVM project on SourceForge
(http://sourceforge.net/project/showfiles.php?group_id=26000). I'm
announcing this for Robert, partly cos he's busy PhD'ing, partly cos I use
it in ByteCodeRuby -- Ruth really is excellent if you want access to the
internals of the Ruby parser.

From the readme
==============

Author: Robert Feldt, [e-mail]

What is it?
-----------
Ruby extension giving classes and functions to access Ruby internals.
Currently includes:

 * ruth/mri, Ruby::Interpreter.parse
    Gives a tree representing the internal parse tree used to execute a Ruby
program.
 * ruth/mri, Ruby::Interpreter.method_body
    Returns the tree for the body of a method.

And a painfully incomplete:

 * ruth/parser, Ruby.parse
    Parse Ruby source code into an abstract syntax tree. Currently uses
RubySchema from Mathieu Bouchard's MetaRuby project to represent the AST's.
Its a cheato-RubyInRuby parser since it looks like one but actually uses
Matz's Ruby Interpreter's parser and then simply transforms the output.
Advantage of this is that it parses exactly the same programs as MRI parses
(since it uses the same parser). Disadvantage is that it relies on C code,
isn't customizable etc.
