*inferior-lisp* bufferSLIME internally uses the comint package to start Lisp
processes. This has a few user-visible consequences, some good and
some not-so-terribly. To avoid confusion it is useful to understand
the interactions.
The buffer *inferior-lisp* contains the Lisp process's own
top-level. This direct access to Lisp is useful for troubleshooting,
and some degree of SLIME integration is available using the
inferior-slime-mode. Many people load the better integrated SLIME
REPL contrib module (see REPL) and ignore
the *inferior-lisp* buffer. (see Loading Contribs for
information on how to enable the REPL.)
