<h4>DebugBase.fix_frame_filename</h4>
<b>fix_frame_filename</b>(<i>frame</i>)
<p>
        Public method used to fixup the filename for a given frame.
</p><p>
        The logic employed here is that if a module was loaded
        from a .pyc file, then the correct .py to operate with
        should be in the same path as the .pyc. The reason this
        logic is needed is that when a .pyc file is generated, the
        filename embedded and thus what is readable in the code object
        of the frame object is the fully qualified filepath when the
        pyc is generated. If files are moved from machine to machine
        this can break debugging as the .pyc will refer to the .py
        on the original machine. Another case might be sharing
        code over a network... This logic deals with that.
