Cat is a functional stack-based programming language inspired by
the Joy programming language.
The primary differences is that Cat provides a static type system with type inferencing
(like ML or Haskell), and a term rewriting macro language extension language called
Cat is a high-level intermediate language translation that can also be used as a stand alone language for
simple application development. In this way it occupies a similar niche to PostScript. Cat is also
an appropriate language for teaching of basic programming concepts.

The following are Cat implementations are currently under active development:
Development on the following Cat implementations are in suspended animation, but may be revived at any time:
The primary implementation of Cat is the C# interpreter and MSIL compiler written by Christopher Diggins,
that is compatible with Mono. A self-installing package of the C#
of the interpreter can be downloaded through
Google code hosting. Cat on Mono may not work with graphics enabled on all platforms. I have included
build files (.bat) and an executable for non-graphics builds.
The source code to the C# intepreter can be either browsed online,
or it can be downloaded anonymously using a subversion CVS client (I use Tortoise SVN):
svn checkout http://cat-language.googlecode.com/svn/trunk/ cat-language
If you find any bugs in the interpreter, or desire any features please submit them using the
issue reporting form.
Cat is completely open-source and the source code is dedicated to the public domain. This means all source files
can be used or modified for any purpose, without restriction, obligation, or warrantee. If you are interested in
consulting services related to Cat please contact the lead developer and designer
