#!/usr/bin/env python
#
# update-wordpress-page: updates a Wordpress page with the contents
# of the input file
#
# Described on http://free-electrons.com/blog/automated-wp-page-updates/
# Download: git.free-electrons.com/training-scripts/tree/wordpress
#
# Usage: update-wordpress-page url-base post-id content-file
#
# Example: update-wordpress-page myblog.com 245 page-contents
#
# For each url-base, the $HOME/.update-wordpress-page file
# should give the wordpress user and password
#
# Multiple wordpress sites are supported.
#
# Tested with Python 2.6 to 2.7, WordPress 3.0 to 3.3
#
# Advantage: you don't have to leave a direct database connection
# to your website open, and don't have to understand
# the WordPress database.
#
# Requirements (tested on Ubuntu 12.04):
# wget http://pypi.python.org/packages/source/C/ClientForm/ClientForm-0.2.10.tar.gz
# tar zxf ClientForm-0.2.10.tar.gz
# cd ClientForm-0.2.10
# sudo apt-get install python-setuptools
# python setup.py build
# sudo python setup.py install
#
