DESCRIPTION
       The  tcl::transform::identity  package  provides  a  command creating an identity channel transformation,
       which does nothing but pass the read and written bytes through it unchanged.  Not  really  useful  in  an
       application,  however as the prototypical observer transformation its code is a useful starting point for
       any other observers people may wish to write.

       The transformations in this module  which  derived  from  identity's  code  are  tcl::transform::adler32,
       tcl::transform::counter, tcl::transform::crc32, and tcl::transform::observe.

       The  internal  TclOO  class implementing the transform handler is a sub-class of the tcl::transform::core
       framework.


API
       ::tcl::transform::identity chan
              This command creates an identity transformation on top of the channel chan and returns its handle.
