Adding source code to Latex in a similar way that it is done in HTML

Is your feature request related to a problem? Please describe. I'm using sphinx.ext.viewcode to link the source code when I generate the html. That works well, when I press source, I can see the original code in the web page.

However, when generating the latex version, I can't add the source code in the pdf.

Describe the solution you'd like I would like to be able to have in the latex document the docstrings of my classes and a link to the original code (all in the same document).
