Gravatar plugin for Pelican
===========================
This plugin assigns the ``author_gravatar`` variable to the Gravatar URL and
makes the variable available within the article's context.
Settings:
---------
Add AUTHOR_EMAIL to your settings file to define the default author's email
address. Obviously, that email address must be associated with a Gravatar
account.
Article metadata:
------------------
:email: article's author email
If one of them are defined, the author_gravatar variable is added to the
article's context.
