+| page of the User Guide.
+|
+| -------------------------------------------------------------------
+| 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
+|    ['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
