DESCRIPTION
       The  tcl::transform::spacer package provides a command creating a chan-
       nel transformation which adds spacing to the data written  to  it,  and
       removes such spacing from the data read from it.

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

API
       ::tcl::transform::spacer chan n ?space?
              This command creates a spacer transformation on top of the chan-
              nel chan and returns its handle.

              The space character sequence will be added every n bytes of data
              written, and on the read side the same is done in  reverse,  re-
              moving  the  spacing. If space is not specified it defaults to a
              single space character (ASCII 32).
