src/cold/chill.lisp

   1 ;;;; This file is not used at cold load time. Instead, it can be
   2 ;;;; loaded into an initialized SBCL to get it into a nostalgic frame
   3 ;;;; of mind, remembering the way things were in cold init, so that it
   4 ;;;; can READ code which is ordinarily read only when bootstrapping.
   5 ;;;; (This can be useful when debugging the system, since the debugger
   6 ;;;; likes to be able to read the source for the code. It can also be
   7 ;;;; useful when experimenting with patches on a running system.)

   9 ;;;; This software is part of the SBCL system. See the README file for
  10 ;;;; more information.
  11 ;;;;
  12 ;;;; This software is derived from the CMU CL system, which was
  13 ;;;; written at Carnegie Mellon University and released into the
  14 ;;;; public domain. The software is in the public domain and is
  15 ;;;; provided with absolutely no warranty. See the COPYING and CREDITS
  16 ;;;; files for more information.
