The [configure:database|INFO] task configures the database DSN
for a project:

  [./symfony configure:database mysql:host=localhost;dbname=example root mYsEcret|INFO]

By default, the task change the configuration for all environment. If you want
to change the dsn for a specific environment, use the [env|COMMENT] option:

  [./symfony configure:database --env=dev mysql:host=localhost;dbname=example_dev root mYsEcret|INFO]

To change the configuration for a specific application, use the [app|COMMENT] option:

  [./symfony configure:database --app=frontend mysql:host=localhost;dbname=example root mYsEcret|INFO]

You can also specify the connection name and the database class name:

  [./symfony configure:database --name=main --class=sfDoctrineDatabase mysql:host=localhost;dbname=example root|INFO]

WARNING: The [propel.ini|COMMENT] file is also updated when you use a [Propel|COMMENT] database
and configure for [all|COMMENT] environments with no [app|COMMENT].
