/**
 * @file
 * Drupal site-specific configuration file.
 *
 * IMPORTANT NOTE:
 * This file may have been set to read-only by the Drupal installation
 * program. If you make changes to this file, be sure to protect it again
 * after making your modifications. Failure to remove write permissions
 * to this file is a security risk.
 *
 * The configuration file to be loaded is based upon the rules below.
 *
 * The configuration directory will be discovered by stripping the
 * website's hostname from left to right and pathname from right to
 * left. The first configuration file found will be used and any
 * others will be ignored. If no other configuration file is found
 * then the default configuration file at 'sites/default' will be used.
 *
 * For example, for a fictitious site installed at
 * http://www.drupal.org/mysite/test/, the 'settings.php'
 * is searched in the following directories:
 *
 *  1. sites/www.drupal.org.mysite.test
 *  2. sites/drupal.org.mysite.test
 *  3. sites/org.mysite.test
 *
 *  4. sites/www.drupal.org.mysite
 *  5. sites/drupal.org.mysite
 *  6. sites/org.mysite
 *
 *  7. sites/www.drupal.org
 *  8. sites/drupal.org
 *  9. sites/org
 *
 * 10. sites/default
 *
 * If you are installing on a non-standard port number, prefix the
 * hostname with that number. For example,
 * http://www.drupal.org:8080/mysite/test/ could be loaded from
 * sites/8080.www.drupal.org.mysite.test/.

/**
 * Database settings:
 *
 * The $databases array specifies the database connection or
 * connections that Drupal may use.  Drupal is able to connect
 * to multiple databases, including multiple types of databases,
 * during the same request.
 *
 * Each database connection is specified as an array of settings,
 * similar to the following:
 *
 * array(
 *   'driver' => 'mysql',
 *   'database' => 'databasename',
 *   'username' => 'username',
 *   'password' => 'password',
 *   'host' => 'localhost',
 *   'port' => 3306,
 * );
 *
 * The "driver" property indicates what Drupal database driver the
 * connection should use.  This is usually the same as the name of the
 * database type, such as mysql or sqlite, but not always.  The other
 * properties will vary depending on the driver.  For SQLite, you must
 * specify a database file name in a directory that is writable by the
 * webserver.  For most other drivers, you must specify a
 * username, password, host, and database name.
 *
 * Some database engines support transactions.  In order to enable
 * transaction support for a given database, set the 'transactions' key
 * to TRUE.  To disable it, set it to FALSE.  Note that the default value
 * varies by driver.  For MySQL, the default is FALSE since MyISAM tables
 * do not support transactions.
 *
 * For each database, you may optionally specify multiple "target" databases.
 * A target database allows Drupal to try to send certain queries to a
 * different database if it can but fall back to the default connection if not.
 * That is useful for master/slave replication, as Drupal may try to connect
 * to a slave server when appropriate and if one is not available will simply
 * fall back to the single master server.
 *
 * The general format for the $databases array is as follows:
 *
 * $databases['default']['default'] = $info_array;
 * $databases['default']['slave'][] = $info_array;
 * $databases['default']['slave'][] = $info_array;
 * $databases['extra']['default'] = $info_array;
 *
 * In the above example, $info_array is an array of settings described above.
 * The first line sets a "default" database that has one master database
 * (the second level default).  The second and third lines create an array
 * of potential slave databases.  Drupal will select one at random for a given
 * request as needed.  The fourth line creates a new database with a name of
 * "extra".
 *
 * For a single database configuration, the following is sufficient:
 *
 * $databases['default']['default'] = array(
 *   'driver' => 'mysql',
 *   'database' => 'databasename',
 *   'username' => 'username',
 *   'password' => 'password',
 *   'host' => 'localhost',
 * );
 *
 * You can optionally set prefixes for some or all database table names
 * by using the $db_prefix setting. If a prefix is specified, the table
 * name will be prepended with its value. Be sure to use valid database
 * characters only, usually alphanumeric and underscore. If no prefixes
 * are desired, leave it as an empty string ''.
 *
 * To have all database names prefixed, set $db_prefix as a string:
 *
 *   $db_prefix = 'main_';
 *
 * To provide prefixes for specific tables, set $db_prefix as an array.
 * The array's keys are the table names and the values are the prefixes.
 * The 'default' element holds the prefix for any tables not specified
 * elsewhere in the array. Example:
 *
 *   $db_prefix = array(
 *     'default'   => 'main_',
 *     'users'      => 'shared_',
 *     'sessions'  => 'shared_',
 *     'role'      => 'shared_',
 *     'authmap'   => 'shared_',
 *   );
 *
 * You can also use db_prefix as a reference to a schema/database. This maybe
 * useful if your Drupal installation exists in a schema that is not the default
 * or you want to access several databases from the same code base at the same
 * time.
 * Example:
 *
 *  $db_prefix = array(
 *    'default' => 'main.',
 *     'users'      => 'shared.',
 *     'sessions'  => 'shared.',
 *     'role'      => 'shared.',
 *     'authmap'   => 'shared.',
 *  );
 *
 * NOTE: MySQL and SQLite's definition of a schema is a database.
 *
 * Database configuration format:
 *   $databases['default']['default'] = array(
 *     'driver' => 'mysql',
 *     'database' => 'databasename',
 *     'username' => 'username',
 *     'password' => 'password',
 *     'host' => 'localhost',
 *   );
 *   $databases['default']['default'] = array(
 *     'driver' => 'pgsql',
 *     'database' => 'databasename',
 *     'username' => 'username',
 *     'password' => 'password',
 *     'host' => 'localhost',
 *   );
 *   $databases['default']['default'] = array(
 *     'driver' => 'sqlite',
 *     'database' => '/path/to/databasefilename',
 *   );
 */
