% This file redefines the start-up routine for PSLCOMP to read and interpret
% the program command string as a list of source files to be compiled.

% Edit by Cris Perdue,  8 Apr 1983 1401-PST
% Compile-files now does exitlisp rather than quit.
%  EvIn is only given a definition if not already defined.
%  Syntax is assumed to be LISP if given a crazy file extension.
% Edit by Cris Perdue,  5 Apr 1983 1421-PST
% Changed to use get-command-args rather than get-command-string
%  and parse-command-string.
%  Uses EVIN to read the file, thus compiles any type of file.
%  If no extension specified, tries "sl", "build", and "red" extensions.
%  Defines EVIN to load RLISP if needed.  This also gets around the
%  problem of starting up in the RLISP top level with RLISP
%  loaded.
%  Now uses ErrSet rather than ErrorSet.
% 8-Dec-82 Alan Snyder
%   Changed use of DSKIN (now an EXPR).
