Posts a Pelican article link & title to Twitter.

# Posts a Pelican article to Twitter. 

# usage: post_to_twitter.py -a articlename
# (articlename is the filename, minus the extension)
# The script will look for articlename.md inside /content, parse out Title & Slug,
# then tweet out "%title% %siteurl%/%slug%.html" under your account.

# Requirements: 
# * Pelican. 
# * At least one Pelican article, already published. 
# * `pip install twitter`. 

# Usage: 
# Put this script in your Pelican directory, add the 
# required keys to your pelicanconf.py, then 
# `python post_to_twitter.py -a articlename`. Confirm the tweet text by hitting enter. 

# Warnings: 
# This is VERY specific to my setup... I use .md and keep all my articles
# in /contents, and I use the same slug as my article name. Also, my site
# is setup as sitename.com/slug.html.

# Maybe this would be a good Penguin plugin, if Penguin gave us a way to know about new articles.
