## Introduction ##

Parse_trans was written in order to capture some useful patterns in parse transformation
and code generation for Erlang.

Most notably, perhaps, the module [`exprecs`](http://github.com/uwiger/parse_trans/blob/master/doc/exprecs.md) generates standardized accessor
functions for records, and [`ct_expand`](http://github.com/uwiger/parse_trans/blob/master/doc/ct_expand.md) makes it possible to evaluate an
expression at compile-time and substitute the result as a compile-time constant.

Less known modules, perhaps:
* [`parse_trans_pp`](http://github.com/uwiger/parse_trans/blob/master/doc/parse_trans_pp.md) can be called with escript to pretty-print source from
  debug-compiled .beam files.
* [`parse_trans_codegen`](http://github.com/uwiger/parse_trans/blob/master/doc/parse_trans_codegen.md) provides pseudo-functions that can be used for
  simple code generation.
* [`parse_trans`](http://github.com/uwiger/parse_trans/blob/master/doc/parse_trans.md) provides various helper functions for traversing code and
  managing complex parse transforms
