#  Update Drupal 6 or 7 core locally, then remotely via SSH and SVN
#
#  Author: Chad Kieffer, ckieffer at gmail dot com
#
#  This script updates a local subversion working copy of Drupal 6 or 7 and then the corresponding 
#  remote production copy. The root .htaccess file in both the working and remote copies is 
#  not touched. Updates to the .htaccess file must be managed manually. The sites/example.sites.php
#  introduced in Drupal 7 is not touched either. 
#
#  Install/Configure
#  1) Save the script locally and make it executable
#  2) Set path and connection variables in drupal_info.sh
#  
#  Use:
#  1) Download Drupal core update from drupal.org to the $DownloadsPath specified in drupal_info.sh
#  2) Run the script, ./drupal_update.sh
#  3) Follow the instructions provided
#
#  @TODO Handle file deletions via svn remove
#  @TODO Support -dev versions
