-/**
- * @file
- * Configuration file for multi-site support and directory aliasing feature.
- *
- * This file is required for multi-site support and also allows you to define a
- * set of aliases that map hostnames, ports, and pathnames to configuration
- * directories in the sites directory. These aliases are loaded prior to
- * scanning for directories, and they are exempt from the normal discovery
- * rules. See default.settings.php to view how Drupal discovers the
- * configuration directory when no alias is found.
- *
- * Aliases are useful on development servers, where the domain name may not be
- * the same as the domain of the live server. Since Drupal stores file paths in
- * the database (files, system table, etc.) this will ensure the paths are
- * correct when the site is deployed to a live server.
- *
- * To activate this feature, copy and rename it such that its path plus
- * filename is 'sites/sites.php'.
- *
- * Aliases are defined in an associative array named $sites. The array is
- * written in the format: '<port>.<domain>.<path>' => 'directory'. As an
- * example, to map http://www.drupal.org:8080/mysite/test to the configuration
- * directory sites/example.com, the array should be defined as:
- * @code
- * $sites = array(
- *   '8080.www.drupal.org.mysite.test' => 'example.com',
- * );
- * @endcode
- * The URL, http://www.drupal.org:8080/mysite/test/, could be a symbolic link or
- * an Apache Alias directive that points to the Drupal root containing
- * index.php. An alias could also be created for a subdomain. See the
- * @link http://drupal.org/documentation/install online Drupal installation guide @endlink
- * for more information on setting up domains, subdomains, and subdirectories.
- *
- * The following examples look for a site configuration in sites/example.com:
- * @code
- * URL: http://dev.drupal.org
- * $sites['dev.drupal.org'] = 'example.com';
- *
- * URL: http://localhost/example
- * $sites['localhost.example'] = 'example.com';
- *
- * URL: http://localhost:8080/example
- * $sites['8080.localhost.example'] = 'example.com';
- *
- * URL: http://www.drupal.org:8080/mysite/test/
- * $sites['8080.www.drupal.org.mysite.test'] = 'example.com';
- * @endcode
- *
- * @see default.settings.php
- * @see conf_path()
- * @see http://drupal.org/documentation/install/multi-site
