   3 # reddit dev environment installer
   4 # --------------------------------
   5 # This script installs a reddit stack suitable for development. DO NOT run this
   6 # on a system that you use for other purposes as it might delete important
   7 # files, truncate your databases, and otherwise do mean things to you.
   8 #
   9 # By default, this script will install the reddit code in the current user's
  10 # home directory and all of its dependencies (including libraries and database
  11 # servers) at the system level. The installed reddit will expect to be visited
  12 # on the domain "reddit.local" unless specified otherwise.  Configuring name
  13 # resolution for the domain is expected to be done outside the installed
  14 # environment (e.g. in your host machine's /etc/hosts file) and is not
  15 # something this script handles.
  16 #
  17 # Several configuration options (listed in the "Configuration" section below)
  18 # are overridable with environment variables. e.g.
  19 #
  20 #    sudo REDDIT_DOMAIN=example.com ./install/reddit.sh
