DESCRIPTION
       The  tcl::chan::random package provides a command creating random channels, i.e. read-only channels which
       return an infinite stream of pseudo-random characters  upon  reading.  This  is  similar  to  the  random
       channels provided by the package Memchan, except that this is written in pure Tcl, not C, and uses a much
       simpler generator as well. On the other hand, Memchan is usable with Tcl 8.4  and  before,  whereas  this
       package requires Tcl 8.5 or higher, and TclOO.

       The  internal  TclOO  class  implementing  the  channel  handler  is a sub-class of the tcl::chan::events
       framework.


API
       ::tcl::chan::random seed
              This command creates a new random channel and returns its handle.  The seed is a list  of  integer
              numbers used to initialize the internal feedback shift register of the generator.
