Update of /project/movitz/cvsroot/movitz/losp
In directory common-lisp.net:/tmp/cvs-serv20160

Modified Files:
	los0.lisp 
Log Message:
The repl package was renamed, so the init defpackage form needs
updating too. The other changes to this file is just my messing around
with testing various bits and pieces.
