Linux 2.6 - man page for erl_id_trans (linux section 3erl)

erl_id_trans(3erl)		     Erlang Module Definition		       erl_id_trans(3erl)

NAME
       erl_id_trans - An Identity Parse Transform

DESCRIPTION
       This module performs an identity parse transformation of Erlang code. It is included as an
       example for users who may wish to write	their  own  parse  transformers.  If  the  option
       {parse_transform,Module}  is  passed to the compiler, a user written function parse_trans-
       form/2 is called by the compiler before the code is checked for errors.

EXPORTS
       parse_transform(Forms, Options) -> Forms

	      Types  Forms = [erlang_form()]
		     Options = [compiler_options()]

	      Performs an identity transformation on Erlang forms, as an example.

PARSE TRANSFORMATIONS
       Parse transformations are used if a programmer wants to use Erlang syntax, but  with  dif-
       ferent semantics. The original Erlang code is then transformed into other Erlang code.

   Note:
       Programmers  are strongly advised not to engage in parse transformations and no support is
       offered for problems encountered.
