-|
-| -------------------------------------------------------------------
-| EXPLANATION OF VARIABLES
-| -------------------------------------------------------------------
-|
-|	['hostname'] The hostname of your database server.
-|	['username'] The username used to connect to the database
-|	['password'] The password used to connect to the database
-|	['database'] The name of the database you want to connect to
-|	['dbdriver'] The database type. ie: mysql.  Currently supported:
-				 mysql, mysqli, postgre, odbc, mssql, sqlite, oci8
-|	['dbprefix'] You can add an optional prefix, which will be added
-|				 to the table name when using the  Active Record class
-|	['pconnect'] TRUE/FALSE - Whether to use a persistent connection
-|	['db_debug'] TRUE/FALSE - Whether database errors should be displayed.
-|	['cache_on'] TRUE/FALSE - Enables/disables query caching
-|	['cachedir'] The path to the folder where cache files should be stored
-|	['char_set'] The character set used in communicating with the database
-|	['dbcollat'] The character collation used in communicating with the database
-|				 NOTE: For MySQL and MySQLi databases, this setting is only used
-| 				 as a backup if your server is running PHP < 5.2.3 or MySQL < 5.0.7
-|				 (and in table creation queries made with DB Forge).
-| 				 There is an incompatibility in PHP with mysql_real_escape_string() which
-| 				 can make your site vulnerable to SQL injection if you are using a
-| 				 multi-byte character set and are running versions lower than these.
-| 				 Sites using Latin-1 or UTF-8 database character set and collation are unaffected.
-|	['swap_pre'] A default table prefix that should be swapped with the dbprefix
-|	['autoinit'] Whether or not to automatically initialize the database.
-|	['stricton'] TRUE/FALSE - forces 'Strict Mode' connections
-|							- good for ensuring strict SQL while developing
-|
-| The $active_group variable lets you choose which connection group to
-| make active.  By default there is only one group (the 'default' group).
-|
-| The $active_record variables lets you determine whether or not to load
-| the active record class
