"""
Members info plugin for Pelican
===============================

This plugin looks for a ``members`` metadata header containing key/value pairs
and makes them available for use in templates

The first line of the members metadata defines each key, and the following
lines contain corresponding values for each member.

:members: nome, email, twitter, github, site_nome, site_href
