______________________________________________________________________________
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.
