## Setup a Drupal site with CiviCRM configured for unit-testing.
## If a site already exists, destroy and recreate it.
## Usage: mk-drupal-test-site <domain.name> <db_name> </path/to/drupal> </path/to/civi>

## SOURCE:
## https://github.com/civicrm/civicrm-core/blob/master/tools/scripts/mk-drupal-test-site

## Pre-requisites:
## - MySQL admin credentials in ~/.my.cnf
## - Apache vhost with mod_rewrite, etc
## - DNS or /etc/hosts entries for "url"
## - Drupal source tree
## - CiviCRM source tree (outside the drupal root)
## - makepasswd
## - drush
## - (strongly recommended) filesystem with "acl" support

Usage: mk-drupal-test-site SITE_URL DB_NAME DRUPAL_ROOT [CIVI_ROOT]
Re/creates a Drupal-based CiviCRM site.

  * SITE_URL: URL of the site. Example: example.org
  * DB_NAME: MySQL database name. Example: civicrm_test
  * DRUPAL_ROOT: Root path of the Drupal website. Example: /var/www/
  * CIVI_ROOT: Root path of the CiviCRM directory. Will be symlinked.
    You probably want to have a separate version somewhere to avoid
    cloning a new version of the code base for each CMS.
    The CiviCRM directory can either contain the main git repositories,
    or an equivalent of the tar.gz archive.
    Example: /srv/repositories/civicrm/
  * SQL_DUMP (optional): instead of a standard blank install, import a
    specific .sql dump. You can specify two .sql files.
