   gem.summary       = %q{CanBe allows you to track the type of your ActiveRecord model in a consistent simple manner.  With just a little configuration on your part, each type of record can contain different attributes that are specifc to that type of record.  From a data modelling perspective this is preferred over ActiveRecord STI since you will not have many columns in your database that have null values.  Under the hood, CanBe uses one-to-one Polymorphic Associations to accomplish the different attributes per type.}
