# Drupal site deploy tool. Install and setup Drupal from a distribution file.
#
# See drupal_site_deploy.sh --help for further parameters and examples.
#
# Basic deployment flow:
#   1. clean-up destination directory (optional)
#   2. extract dist tarball to destination with proper permissions,
#      create settings.php and files directory under sites/default
#   3. install drupal with drush si command, setup admin password and 
#      proper filename, and repair sites/default/files ownership
#   4. create flag-file that marks successfull installation (optional)
