Author URL Directive
This adds a link to the author name in postmeta.
Simply add it to your extensions in conf.py:
# Add other Sphinx extensions here
extensions = [..., 'authorurl-directive']
and specify a default URL:
author_url = 'http://www.yoursite.com/pages/about.html#about-me'
Usage:
Add .. author_url:: default or .. author_url:: http://site.com/ to posts where you want to add a website link to an author.
