This too is done :-)  I was taking a look at ASDF-INSTALL.  It seems
complicated but it is one of those things we must do to make life easy
for the masses.

I myself use ASDF to load LoGS everytime (since SBCL includes it by default).

If it is all right with you, shall I add a file named "cl-cli.asd" to
the repository?  I have one on my disk and I copy it each and every
time I check out the latest version.  It'll be better to just add it
to the repository, IMO.

Here's the file.  It is a severely stripped down version of logs.asd :)

;;; -*- Mode: LISP; Syntax: COMMON-LISP; Package: CL-USER; Base: 10 -*-
(defsystem "cl-cli"
   :description "Command line processing utility"
   :version "0.0.1-pre"
   :author "James E. Prewett <address@hidden>"
   :licence "GPL"
   :depends-on ()
   :components ((:file "cl-cli")))

I took the version number from cl-cli-version

Thanks Jim
