Here's a collection of scripts covering various stages of the pipeline. Most of them are tool applications and come complete with a professional gui.

The Python Scripts are mostly conversions from Mel Scripts. To run them, you will need to load them into the script editor and then <cntl-a> followed by <cntl-enter>. Then you can enter the name of the main function which is the same of the script. For example, load and execute "gui.py" then type gui() on the Python Command Line.
