Installing Dependencies on Ubuntu 12.04

DBNAME="foodb"

# This script installs dependencies for CommCare HQ on Ubuntu 12.04 (Java,
# Jython, couchdb, couchdb-lucene, less, uglifyjs, and various python packages)
# and sets couchdb and couchdb-lucene up to automatically run on startup.  It
# also creates postgres (user 'django', pass 'django') and couchdb databases
# named according to $DBNAME as specified above. 

# Before running, you must download the following files to the script's
# directory: 
#  - the JDK 7 tar.gz from
#    http://www.oracle.com/technetwork/java/javase/downloads/index.html and
#    save it as jdk.tar.gz
# 
#  - jython_installer-2.5.2.jar from http://jython.org/downloads.html
#
#  - apache-couchdb-1.2.0.tar.gz from http://couchdb.apache.org/#download
