Preprocessor generator for Python
---------------------------------

EasyExtend (EE) is a preprocessor generator and metaprogramming framework
written in pure Python and integrated with CPython. The main purpose of
EasyExtend is the creation of extension languages i.e. adding custom syntax and
semantics to Python. EasyExtend comes out of the box as a single package with no
dependecies other than those to Pythons standard library.

Parser generator
----------------

EasyExtend provides a powerful parser generator for top down parsers called
Trail. Trail parsers are trace based, non-backtracking parsers with one token of
lookahead but the capability of an LL(k) parsers for arbitary k. Trails
nondeterministic finite automata (NFAs) are used for multiple tasks: most
obviously for parsing but also for lexical analysis, parse tree validation and
generation of parse tree builders.

Blank slate programming languages
---------------------------------

Besides the main goal of providing a system for generating extensions languages,
EasyExtend can also be used to build languages from the scratch targeting
Pythons virtual machine.

Source inspection and manipulation
------------------------------------

EasyExtend provides csttools which is a library for inspection, modification and
synthesis of parse trees.
