# Very simple Python program to publish the last RSS entry of a feed
# in a Facebook Page. It shows the blogs available and allows to
# select one of them.
# 
# It has a configuration file with a number of blogs with:
#	- The RSS feed of the blog
#	- The Twitter account where the news will be published
#	- The Facebook page where the news will be published
# It uses a configuration file that has two sections:
#  	- The oauth access token
#
