For make a UCW App, currently the best way is to use the clbuild software facilities:

1. Get clbuild

darcs get http://common-lisp.net/project/clbuild/clbuild

Make it executable

$ cd clbuild
clbuild$ chmod +x clbuild

Check clbuild has all the dependencies it needs

clbuild$ ./clbuild check

2 With clbuild get ucw and its dependencies.

./clbuild install ucw

3 Using clbuild generate the ~/.emacs code to load the clbuild and slime software, put that code into your ~/.emacs

./clbuild slime-configuration

;; add this to your ~/.emacs to use clbuild and its slime:
;;

;; possibly controversial as a global default, but shipping a lisp
;; that dies trying to talk to slime is stupid, so:
(set-language-environment "UTF-8")
(setq slime-net-coding-system 'utf-8-unix)

;; load slime:
(setq load-path (cons "/home/jdoe/src/clbuild/source/slime" load-path))
(setq load-path (cons "/home/jdoe/src/clbuild/source/slime/contrib" load-path))
(setq slime-backend "/home/jdoe/src/clbuild/.swank-loader.lisp")
(setq inhibit-splash-screen t)
(load "/home/jdoe/src/clbuild/source/slime/slime")
(setq inferior-lisp-program "/home/jdoe/src/clbuild/clbuild lisp")
(setq slime-use-autodoc-mode nil)
(slime-setup '(slime-fancy slime-tramp slime-asdf))
(slime-require :swank-listener-hooks)
(slime)

4 Fire up your clbuild-turbo-charged Emacs!!

5 On Emacs, load UCW:

cl-user> (require :ucw)

6 Entering into UCW context:

CL-USER> (in-package :ucw-user)
#
UCW-USER>

7 Enjoy!
