Type HELP for debugger help, or (SB-EXT:QUIT) to exit from SBCL.

restarts (invokable by number or by possibly-abbreviated name):
  0: [MACSYMA-QUIT] Maxima top-level
  1: [CONTINUE    ] Ignore runtime option --eval "(cl-user::run)".
  2: [ABORT       ] Skip rest of --eval and --load options.
  3:                Skip to toplevel READ/EVAL/PRINT loop.
  4: [QUIT        ] Quit SBCL (calling #'QUIT, killing the process).
