+  <description>
+    <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 <c>{parse_transform,Module}</c> is passed
+      to the compiler, a user written function <c>parse_transform/2</c>
+      is called by the compiler before the code is checked for
+      errors.</p>

+    <title>Parse Transformations</title>
+    <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.
+      </p>
+    <note>
+      <p>Programmers are strongly advised not to engage in parse transformations and no support is offered for problems encountered.</p>
