MULTIPLE PROCESS SUPPORT
===========================================================================
Cmuscheme.el supports, in a fairly simple fashion, running multiple Scheme
-processes. To run multiple Scheme processes, you start the first up with
-\\[run-scheme]. It will be in a buffer named *scheme*. Rename this buffer
-with \\[rename-buffer]. You may now start up a new process with another
-\\[run-scheme]. It will be in a new buffer, named *scheme*. You can
