=== DKAN INIT SCRIPT. v0.1 ===

This script will initialize the dkan install profile or a dkan-submodule to prepare a full drupal site. It should be run only once to set that up.

For DKAN core:
--------------
  Usage: bash dkan-init.sh dkan

  What it does:
    - Moves everything in the current folder into a new ./dkan subfolder
    - Creates an initial ahoy.yml file based on dkan/.ahoy/starter.ahoy.yml

For DKAN submodules:
--------------------
  Usage: bash dkan-init.sh dkan_submodule_name

  What it does:
    - Moves everything in the current folder into a temporary ./dkan_submodule_name subfolder
    - Clones dkan from git@github.com:NuCivic/dkan.git into a new ./dkan folder
    - Moves ./dkan_submodule_name to ./dkan/modules/dkan/dkan_submodule_name
    - Creates an initial ahoy.yml file based on dkan/.ahoy/starter.ahoy.yml

Automatically installing dependencies:
--------------------------------------
  Usage: bash dkan-init.sh dkan [--install-dependencies | --deps ]

  Installs composer, drush (8.0.1), and ahoy (1.1.0). Some commands are run as sudo and may require your password.

Automatically installing dkan:
--------------------------------------
  Usage: bash dkan-init.sh dkan [--build-dkan | --build ] [DB_URL ie. mysql://root:rootpw/localhost/db]

  Builds a full dkan site by running the ahoy commands for you. (See using ahoy). To install to the correct database, you need to supply the dburl to use.

Using ahoy:
-----------
  After you run this script and install ahoy (if you haven't yet), use the 'ahoy' command for additional steps like the following:

  Create a new drupal website in the ./docroot folder:
      ahoy dkan drupal-rebuild [DB_URL i.e. mysql://user:password@server/database_name]"

  Run drush make to install all the dkan dependencies:
      ahoy dkan remake

  Reinstall the drupal database:
      ahoy dkan reinstall

  Internal teams should create a pluto ticket. Others should create a ticket on github.
