This assumes you build your pdf with a Makefile and that the name of the file to build is paper.tex. This can be customized as needed.

Hi @gidden! Recently used this awesome tool. Any chance you'd be alright with me making a repo for it to add some flexibility and features?

Please go ahead @pshriwise, glad it has been of use =)
