\section{The [[BOOT]] package}

Everything in axiom that the user references eventually shows
up here. The interpreter and the algebra are run after switching
to the boot package (in-package "BOOT") so any symbol that the
interpreter or algebra uses has to (cough, cough) appear here.
<<*>>=
<<license>>

(IMPORT-MODULE "sys-constants")
(IMPORT-MODULE "sys-globals")

@

Note that it is confusing the package \Tool{Axiom}'s compiler and
interpreter use is called [[BOOT]].  It should have been
[[Spad]], or better yet [[Axiom]].



\section{Portability issues}

This section discusses some portability issues known to affect
this module.

\subsection{[[compiler-let]]}

The construct [[compiler-let]] is not part of ANSI Lisp, although
it had been described in CLTL.  Therefore some Lisp implementations
offer it as extensions.

<<non-portable-codes>>=
#+:clisp (import 'ext:compiler-let)
@

<<*>>=

; NAME:	   Boot Package
; PURPOSE: Provide forward references to Boot Code for functions to be at
;	   defined at the boot level, but which must be accessible
;	   not defined at lower levels.

(in-package "BOOT")

<<non-portable-codes>>

(defmacro def-boot-val (p val where)
  `(compiler-let nil
     (defparameter ,p ,val ,where)
     (export '(,p) "BOOT")))
