	I've compiled the version of PCL (Portable CommonLoops) announced
August 28th and filed it in [SUMEX-AIM.Stanford.edu]<LISPUSERS.LYRIC.PCL>
	Basically, to load it, you'd want to grab all the .dfasl files
in that directory and copy them into a directory at your site.  Then
you'd set PCL::*PCL-DIRECTORY* to the pathname of that directory, load
DEFSYS.DFASL, and evaluate (PCL::LOAD-PCL) to load the rest of the
files (20 of them).  The mechanism is described in DEFSYS.LISP.
	After loading PCL, you can load PCL-ENV.DFASL which integrates
PCL more closely into the Xerox Lisp environment; eg. with the inspector.
	As I understand it--and I am no authority on this subject--PCL
is at present the closest portable object-oriented programming system
to CLOS, the pending Common Lisp Object System standard.  It seems to
be a close match to the functions described in section 2 of the
February CLOS specification (filed in CONCEP.DVI and FUNCTI.DVI).  PCL
runs in at least half a dozen different implementations of Common Lisp.
	I hesitate to post PCL on SUMEX, as it makes it no more widely
available than on parcvax and introduces the possibility of version
skew.  Get it from SUMEX at your own risk!  The main reason I make this
posting is for the benefit of people who didn't know PCL existed at all.
	There is a mailing list for users of PCL.  Requests for addition
may be sent to Owners-CommonLoops.PA@Xerox.com
