Parse_transform utilities

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 generates standardized accessor functions for records, and ct_expand 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 can be called with escript to pretty-print source from debug-compiled .beam files.
• parse_trans_codegen provides pseudo-functions that can be used for simple code generation.
• parse_trans provides various helper functions for traversing code and managing complex parse transforms
