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_transform/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 different 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.
