Charles container library usage examples

[David Trudgett <wpower@zeta.org.au.nospamplease>]

Does anyone know where I can find some usage examples for the Charles
container library, or some code that makes use of Charles? 

I've got Charles downloaded and installed on my include path, but as a
newcomer to Ada, I'm having difficulty working out how it is intended
to be used.

The first thing I had in mind to do was to create a simple map, for
example, to translate the following Common Lisp:

(defvar *side-corners*
  '((2 (1 3))
    (4 (1 7))
    (6 (3 9))
    (8 (7 9))))

This is just a simple mapping of four particular integers (2, 4, 6, 8)
to four particular lists each consisting of two integers.

I use it in a function like this:

(defun side-corners (side)
  "Return a list of the (two) corners that flank the given side"
  (second (assoc side *side-corners*)))

so that the function call

(side-corners 2)

returns the list (1 3)


Any pointers to code samples, or other hints would be greatly
appreciated!

Thanks,

David
