DESCRIPTION

12       This module is provides the interface to allow the creation of Source
13       Filters which use a Unix coprocess.
14
15       See Filter::exec, Filter::cpp and Filter::sh for examples of the use of
16       this module.
17
18   filter_add()
19       The function, "filter_add" installs a filter. It takes one parameter
20       which should be a reference. The kind of reference used will dictate
21       which of the two filter types will be used.
22
23       If a CODE reference is used then a closure filter will be assumed.
24
25       If a CODE reference is not used, a method filter will be assumed.  In a
26       method filter, the reference can be used to store context information.
27       The reference will be blessed into the package by "filter_add".
28
29       See Filter::Util::Call for examples of using context information using
30       both method filters and closure filters.
