 # Bash script for settign up Django project on Ubuntu 14 with nginx, python 3,
 # virtualenv, git installed
 # Will create directory structure, clone source code, change Django secret key,
 # set up Nginx conf, set up gunicorn upstart job.
 # Upstart job will be named "site-<project_name>"


 # HOW TO RUN

 # sudo ./set_up_django_proj_ubuntu_14.sh <git_repo_url> <project_domain>
 # Example:
 #     cd /home/someuser/sites
 #     sudo ./set_up_django_proj_ubuntu_14.sh https://github.com/somegithubuser/somedjangorepo.git somedomain.com
