DESCRIPTION

       The  tcl::transform::zlib  package  provides  a  command creating a channel transformation
       which zlib compresses the written data, and decompresses on reading.

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

API

       ::tcl::transform::zlib chan ?level?
              This  command  creates  a zlib compressor transformation on top of the channel chan
              and returns its handle.

              The level specifies how much effort is put into the compression, from 0 to  9,  and
              defaults to 4.
