18.1.6 Examples
</H2>

<P>
The parser modules allows operations to be performed on the parse tree
of Python source code before the bytecode is generated, and provides
for inspection of the parse tree for information gathering purposes.
Two examples are presented.  The simple example demonstrates emulation
of the <tt class="function">compile()</tt><a id='l2h-4956' xml:id='l2h-4956'></a> built-in function and
the complex example shows the use of a parse tree for information
discovery.
