# Install script for CommCare HQ on Ubuntu 12.04
# - installs all dependencies
# - ensures all necessary processes will run on startup
# - creates databases 
#
# 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
# 
# When installing Jython, accept the default options and enter
# /usr/local/lib/jython when prompted for the target directory.


# Database settings; change these if desired
