This directory contains the implementation of closette from the AMOP
book modified for use with XLISP-PLUS 2.1gbc or XLISP-STAT 3.44 or
later.

The .lisp files in this directory are the original files from
ftp.xerox.com in pub/pcl/mop. The .lsp files closette.lsp and
newcl.lsp are modified to work with xlisp or xlispstat. To compile
them, do

	(compile-file "newcl")
	(load "newcl")
	(load "closette.lsp")    ; this is needed to define macros and
	(compile-file "closette"); macroexpansion functions

Once the code is compiled, doing

	(load "newcl")
	(load "closette")

should bring in the compiled code. You can then run the tests with

	(load "closette-tests.lisp")

The changes needed to closette.lisp are very minor. They are

	Change the use of in-package from CLtL1 to CLtL2 conventions

	Modify a defstruct to not use BOA constructors, which are not
	supported in xlisp yet.

A future release of xlispstat will add support for BOA structure
constructors; the second change can then be omitted.
