Ok. Im trying to understand variable_get(). I read so far that you can set variables in the settings.php using the $conf array and retrieve them later in code by using variable_get(). Ive read that you can also use variable_get to retrieve values from the database.

How does this work?

Is there a table that is automatically built?

How would you set variables if this feature is possible?
