Thank you!

I'm using it with the beamer class. I had an issue with the color package:
LaTeX Error: Option clash for package color. [...] The package color has already been loaded with options: []

Removing \usepackage[usenames,dvipsnames]{color} from the preamble and setting the document option xcolor={usenames,dvipsnames} fixed the error.

I report just in case somebody else runs into the same issue.

Thanks for the gist :)
