<h1>eric5.Utilities.ModuleParser</h1>
<p>
Parse a Python module file.
</p><p>
This module is based on pyclbr.py as of Python 2.2.2
</p><p>
<b>BUGS</b> (from pyclbr.py)
<ul>
<li>Code that doesn't pass tabnanny or python -t will confuse it, unless
  you set the module TABWIDTH variable (default 8) to the correct tab width
  for the file.</li>
</ul>
