   ret = nil

   return false if ext.empty?
   driver = @drivers[ext]
   return false if driver.nil?
   driver.each { |d| ret = d.call(name); return ret if ret }
   nil
end

.register(ext, driver) ⇒ Object

Registers a new Asset Driver of a specific extension (i.e. “css”, “js”, etc’)

Multiple Asset Drivers can be registered for the same extension. The will be attempted in the order of their registration.

An Asset Drivers is an object that responsd to ‘.call(target)`. If the traget is newly rendered, the driver should return the rendered text. If the asset didn’t change since the last time ‘.call(target)` was called, the driver should return ’true’ (meanning, yet, the asset exists, it’s the same). If the driver doesn’t locate the asset, it should return ‘nil` or `false`, indicating the next driver should be attempted.
