PyLinda 0.3
By Andrew Wilkinson <aw at cs dot york dot ac dot uk>
Introduction
---------------
Linda is an widely studied distributed computing environment, centred
around the notion of a tuple space. A tuple space is a bag (also called a
multi-set) of tuples. A tuple is an ordered, typed chunk of data. Tuple
spaces exist independently of processes in the system, and the data placed
into a tuple space also exist independently. See "Generative communication
in Linda" (1985) and "Multiple tuple spaces in Linda" both by David
Gelernter for more information on Linda.
PyLinda is a simple implementation of a linda system, however it also
includes several of the more recently proposed extensions to Linda in the
form of multiple tuple spaces, garbage collection, sane non-blocking
primitives and bulk tuple operations.

big if/elif statement.
