This is my first attempt at a make file, so I'm sure it's not complete... but it's a start anyway.
I tried to follow the instructions at the bottom of this page: http://simplytest.me/questions-and-answers
What about modules depending on external libraries?
If your module requires an external library (eg. a jQuery plugin), please read how to automatically resolve such dependencies by make-files.
Simplytest.me will then execute the first makefile it can find. Also please make sure that your makefiles are still up-to-date and working.
