-simplegeneric: Simple single-dispatch generic functions for Python
-==================================================================
-
-Description
------------
-
-Simple generic functions (similar to Python's own len(), pickle.dump(),
-etc.)
-
-The simplegeneric module lets you define simple single-dispatch generic
-functions, akin to Python's built-in generic functions like len() iter()
-and so on. However, instead of using specially-named methods, these
-generic functions use simple lookup tables, akin to those used by e.g.
-pickle.dump() and other generic functions found in the Python standard
-library.
-
-As you can see from the above examples, generic functions are actually
-quite common in Python already, but there is no standard way to create
-simple ones. This library attempts to fill that gap, as generic
-functions are an excellent alternative to the Visitor pattern, as well
-as being a great substitute for most common uses of adaptation.
-
-This library tries to be the simplest possible implementation of generic
-functions, and it therefore eschews the use of multiple or predicate
-dispatch, as well as avoiding speedup techniques such as C dispatching
-or code generation. But it has absolutely no dependencies, other than
-Python 2.4, and the implementation is just a single Python module of
-less than 100 lines.

-# simplegeneric does not strictly require setuptools, but it does try
