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