[Note: the text below is the README that came with the practicals I
distributed when PCL was published in 2005. I'm hoping to update a few
things to allow this code to run in a more modern environment. At some
point I'll update this README.]


This directory contains the source code for _Practical Common Lisp_.
You may use and redestribute this software according to the terms of
the license in file LICENSE.

The code is designed to be loaded with Another System Definition
Facility (ASDF) and each chapter directory contains its own ASD file.
You can either add the name of each ChapterXX directory to
ASDF:*CENTRAL-REGISTRY* or you can create symlinks to the ASD files in
those directories in a directory that is already named in
ASDF:*CENTRAL-REGISTRY*. If you also add this directory to the central
registry or create a symlink to the file practicals.asd you can then
load all the practicals code by typing:

  (asdf:oos 'asdf:load-op :practicals)

at the REPL. You can also load the code for individual chapters by loading the
system of the same name as the ASD file in each ChapterXX directory.

  ./Chapter03/simple-database.asd
  ./Chapter08/macro-utilities.asd
  ./Chapter09/test-framework.asd
  ./Chapter15/pathnames.asd
  ./Chapter23/spam.asd
  ./Chapter24/binary-data.asd
  ./Chapter25/id3v2.asd
  ./Chapter26/url-function.asd
  ./Chapter27/mp3-database.asd
  ./Chapter28/shoutcast.asd
  ./Chapter29/mp3-browser.asd
  ./Chapter31/html.asd

Thus to load the test framework code from Chapter 9, you'd type:

  (asdf:oos 'asdf:load-op :test-framework)

at the REPL. (Note that Chapter31/ contains the code for both Chapters 30 and
31.)

Alternatively, you can download the Practical Common Lisp, Lispbox
distribution from:

  http://www.gigamonkeys.com/lispbox/

which provides the easy-to install Emacs + SLIME Lisp development environment
discussed in the book. That distribution contains all the book's code already
set up to be loaded with ASDF.
