manage meta description tag

[lunika]

the meta tag description is almost empty on every pages.

meta description can be managed at the template level (file in _posts folder). On each file, in the header you can set variables, if the description variable is set, its value will be used in the meta description tag.

example :

---
layout: post
category: api-hours
title: Clermont'ech API Hour #1
description: Api Hour #1 le 3 avril 2013 à 19h.
