SPSC Lite is a minimalistic version of SPSC, which may be useful for
educational purposes and as a starting point for experimenting with
supercompilation.

Until now, there have been 2 versions of SPSC Light written:

* in Scala

* in Haskell
http://code.google.com/p/spsc/source/browse/spsc_lite_haskell
* in Python 2.6
