1""" Rewrite Rules 

2 

3DISCLAIMER: This module is experimental. The interface is subject to change. 

4 

5A rule is a function that transforms one expression into another 

6 

7 Rule :: Expr -> Expr 

8 

9A strategy is a function that says how a rule should be applied to a syntax 

10tree. In general strategies take rules and produce a new rule 

11 

12 Strategy :: [Rules], Other-stuff -> Rule 

13 

14This allows developers to separate a mathematical transformation from the 

15algorithmic details of applying that transformation. The goal is to separate 

16the work of mathematical programming from algorithmic programming.

20strategies.rl - some fundamental rules 

21strategies.core - generic non-SymPy specific strategies 

22strategies.traverse - strategies that traverse a SymPy tree 

23strategies.tools - some conglomerate strategies that do depend on SymPy
