This package consists of a number of Source Filters. For more details see the pod documentation embedded in the .pm files. If you intend using the Filter::Call functionality, I would strongly recommend that you check out Damian Conway's excellent Filter::Simple module. This module provides a much cleaner interface than Filter::Util::Call. Although it doesn't allow the fine control that Filter::Util::Call does, it should be adequate for the majority of applications.
