; This emulation package version is written for Symbolics Common Lisp.
; Emulation commentary refers to LISP/VM, IBM Program Number 5798-DQZ,
; as described in the LISP/VM User's Guide, document SH20-6477-1.
; Main comment section headings refer to sections in the User's Guide.
; If you are using this, you are probably in Common Lisp, yes?
