# This is a script used to deploy the app. After the git repository is updated, this script is

# executed in order to complete the deployment. Feel free to customize with wild abandon. This

# script is executed as root. Thus, it is critically important to sudo untrusted commands.

# Anything from the app should be considered untrusted.

# If any simple command fails, halt the script.

# BASE_DIR - base location for the application (usually /srv/app_name)

# GIT_DIR - location of the app's main git dir

# RAILS_ENV - the environment (production, staging, etc.)

# APP_USER - the user (and group) for the application
