 Don Cohen writes that the code below is problematic. Especially because of
 the DEFVAR form.

 ==== /tmp/build1
 (in-package :cl-user)
 (defpackage "AP5" (:use "CL") (:nicknames "ap5"))
 (in-package :ap5)
 (load "/tmp/compile.lsp" :print t)
 (setf source-default-path "/backup/shuttle/home/don/ap5-2006/foo.lsp"
      bin-default-path "/tmp/build-ap5/foo.fas")
 (ensure-directories-exist bin-default-path)

 (COMPILE-AP5 :recompile t)
 ;;(compile-ap5 :ask t)

 ==== /tmp/compile.lsp
 (in-package "AP5")


 (defvar info nil)
 (defvar ask nil)
 (defvar recompile nil)
 (defvar nevercompile nil)
 (defvar *changed* nil)
 (defvar startfile nil)
 (defvar stopfile t)
 (defvar *start-time* 0)

 (defun compile-ap5 (&key recompile nevercompile info ask
                          (break-at-end #+symbolics t) startfile (stopfile
 t)
                         &aux *changed* (*start-time* (get-universal-time))
                         #+(or symbolics ti) (global:inhibit-fdefine-
 warnings t))
 ; (compile-load "sys-depend")
  (declare (special  generator-cost-record record-expensive-and-costs))
 )
