This Python script parses TAS recordings generated from https://jump.tf/forum/index.php/topic,1350.0.html into Recording, Frame, and Projectile classes with readable attributes for debugging. Each class also has a function to output a string of its contents compatible for use with the original TAS plugin.
See the included IPython notebook tasdebug.ipynb for an example use case for overwriting recording bugs. Read more about this example here: https://jump.tf/forum/index.php/topic,2796.0.html
