# ============================
# DRUSH INSTALLATION SCRIPT
# ============================ 

# Download Drush v3 from D.O and make it work on `drush` (OS X / Linux / *nix).
# Script is designed to be re-run any time Drush needs to be updated.
# Created by stemount, adapted by KarenS.

# Script also retrieves and installs Drush Make, Provision, and Module Builder.
# Those parts can be commented out if not desired.

# We put Drush Make, Provision, and Module Builder in the Drush commands 
# directory to make it easy to wipe and replace them with newer
# versions by re-running this script without affecting
# custom files that might be in the .drush folder.

# ============================
# SETUP
# ============================

# Recommended paths are either ~./drush to enable Drush 
# for a single user or /usr/share/drush to allow 
# all users to use Drush. The final Drush location
# will end up being /usr/share/drush/drush because
# we are extracting files in /usr/share/drush.
# Create the desired directory if it doesn't already
# exist and drop this script into it, then cd into it.
# Be sure to do u+x drush_downloader.sh
# to make the script executable, then execute it.

# Remove current drush (if existent).
rm -rf /usr/share/drush/drush
# Create drush directory in case it does not already exist.
mkdir /usr/share/drush/
# Move to new directory.
cd /usr/share/drush
