Trying to use McCLIM

[Andrea De Michele]

Hello Craig,

I tried your code to see why the commands are disabled.  I think this is
due to the fact that the commands are not inserted in the command table:

--------
CB> (command-present-in-command-table-p 'com-show-info 'cb-file)
NIL
--------

Evidently Symbolics and Franz versions of macro define-command-table
automatically add the commands in :menu argument to the command-table,
mcclim version no.

So you need to add by hand the commands to command-table like that:
---------
(add-command-to-command-table 'com-show-info 'cb-file)
---------

or use the :command-table name option in define command (for this you
need to define the command-table before the command):

-----------
(define-command (com-show-info :command-table cb-file) ()
  ...
  ...)
-----------------
