Your dedicated rigging-shelf - Sourcing multiple script at once to a shelf

I have a tool for organising scripts into menus if that's helpful: https://github.com/morganloomis/ml_tools/blob/master/ml_toolbox.py Basically you just organise yours scripts in folders under an ml_toolbox_menu folder in your script directory, then the script will turn that folder hierarchy into a menu hierarchy on the maya menu bar. Script requirements are that MEL scripts need to have a global proc of the same name as the filename, and python files should have a main() or ui() function to be run.

I just whipped up something quickly to do that. It's a bad bad code, but seems to do the job.

Just change the SHELF_NAME variable to whatever you want to call your shelf and run the code. It will open up a new maya window which is blank and you need to drag your files on to that window. It should create the shelf and exit.

Bear in mind if a shelf with the same name already exists, it will error out.

Tested on Windows 7 - Maya 16.5 and Maya 17
