% This file redefines the start-up routine for PSL (Lisp Reader) to first read
% and interpret the program command string.  If the command string contains a
% recognized command name, then the corresponding function is immediately
% executed and the program QUITs.  Otherwise, the normal top-level function
% definition is restored and invoked as normal.  Commands are defined using the
% property PROGRAM-COMMAND (see below).  This file defines only one command,
% COMPILE, which is used to compile Lisp files (not RLisp files).
