I'm just starting to learn CLOS with an implementation of PCL
and Allegro Common Lisp.  My personal model of object oriented
programming is the SMALLTALK model since I've done a fair
amount of programming in Objective-C.  I only have the 'Common
Lips Object System Specification' for documentation.  For the life
of me I can't figure out how to add a method to a class.  Basically,
I don't really understand the CLOS generic functions I guess.  The
forms that one would think might add a method to a class, e.g., 
add-method, don't even take a class as an argument.  Please help
with explainations or, better yet, simple code examples.  Thanx.
