I completely forgot to mention that you can still specify any variable
you want in start.lisp.  As they are defined with `defvar' in
src/default.lisp, if you set them with `setf' in you start.lisp BEFORE
loading `:ucw.default', they still have the value you've specified
(not the one in src/default.lisp).

Actually, I just found a possible error in src/default.lisp: the last
action is to load the `*ucw-config-file*' if present via
`load-config-file'.  The latter calls `load-applications', to prepare
the necessary variables (`*ucw-applications*' and `*ucw-systems*')
reading the ASDF files present in `*ucw-applications-directory*'.  So,
if `*ucw-config-file*' is empty, `load-applications' is not called.

I think the best solution will be the following in src/default.lisp:

  (if *ucw-config-file*
    (load-config-file)
    (load-applications))

Comments?

Thx, bye,
