NAME
       Filter::Util::Exec - exec source	filter

SYNOPSIS
	   use Filter::Util::Exec;

DESCRIPTION
       This module is provides the interface to	allow the creation of Source
       Filters which use a Unix	coprocess.

       See Filter::exec, Filter::cpp and Filter::sh for	examples of the	use of
       this module.

       Note that the size of the buffers is limited to 32-bit.

   filter_add()
       The function, "filter_add" installs a filter. It	takes one parameter
       which should be a reference. The	kind of	reference used will dictate
       which of	the two	filter types will be used.

       If a CODE reference is used then	a closure filter will be assumed.

       If a CODE reference is not used,	a method filter	will be	assumed.  In a
       method filter, the reference can	be used	to store context information.
       The reference will be blessed into the package by "filter_add".

       See Filter::Util::Call for examples of using context information	using
       both method filters and closure filters.
