<H3>MODULE SUMMARY</H3>
<DIV CLASS=REFBODY>
An Identity Parse Transform
</DIV>
<H3>DESCRIPTION</H3>
<DIV CLASS=REFBODY>
<P>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 <CODE>{parse_transform,Module}</CODE> is passed
to the compiler, a user written function <CODE>parse_transform/2</CODE>
is called by the compiler before the code is checked for
errors.
</DIV>
<H3>EXPORTS</H3>
<P><A NAME="parse_transform/2"><STRONG><CODE>parse_transform(Forms, Options) -> Forms</CODE></STRONG></A><BR>
<DIV CLASS=REFBODY><P>Types:
<DIV CLASS=REFTYPES>
<P>
<STRONG><CODE>Forms = [erlang_form()]</CODE></STRONG><BR>
<STRONG><CODE>Options = [compiler_options()]</CODE></STRONG><BR>
</DIV>
</DIV>
<DIV CLASS=REFBODY>
<P>Performs an identity transformation on Erlang forms, as an example.
</DIV>
<H3>Parse Transformations</H3>
<DIV CLASS=REFBODY>
<P>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.
