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.

   filteradd()
       The function, "filteradd" 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 "filteradd".

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