# NOTE: This converter requires Sequel and the MySQL gems.
# The MySQL gem can be difficult to install on OS X. Once you have MySQL
# installed, running the following commands should work:
# $ sudo gem install sequel
# $ sudo gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config
#
# I run this as follows:
# ruby -r './_import/drupal' -e 'Jekyll::Drupal.process("#{ENV["DB"]}", "#{ENV["DB_USER"]}", "#{ENV["DB_PASS"]}", "#{ENV["DB_HOST"]}")'
#
module Jekyll
module Drupal
# Reads a MySQL database via Sequel and creates a post file for each post
# in wp_posts that has post_status = 'publish'. This restriction is made
# because 'draft' posts are not guaranteed to have valid dates.
