[Seaside] Brush or Component?

[Esteban A. Maringolo]

Hi,

I'm planning to wrap a date picker
(http://www.dynarch.com/projects/calendar/), what is the best approach
I should take?
Use it as a brush, make it a full featured component, or use both?

Is it possible to automatically reference the required css/js when
this wrapper is used, or must be defined explicitly in the containing
component?

Best regards,
