SublimeText2 — plugin / keymap for cleanup ('latexmk -c')

Question

The original question (which has since been edited numerous times) was the beginning of my ongoing quest to deal with the LaTeX auxiliary files using TexLive (MacTeX) on OSX (Snow Leopard and Mountain Lion) with Sublime Text 2.

Jan Hlavacek was kind enough to provide a Bash script-based solution:

Possible to have a shell script containing the whole LaTeX document?

I have since written my own plugin with the assistance John Collins, Ph.D. (author of latexmk.pl), who gave me a Bash command line example latexmk file.tex && latexmk -c file.tex; and, with the assistance of Xymostech, who helped me convert the && into Python format.

Because this is an ongoing journey, there are bits and pieces of the solution in various threads throughout the internet. The best way to keep track of everything appears to be with a github account, which allows me to update the code as my knowledge grows:

Here is my own plugin:

Here is my unofficial modification of the LaTexTools plugin:
