I have been looking at CLtL2, at the conditions section, and have used
conditions in other languages, but I don't quite understand the usage
of conditions.  What I would like is someone to send me a short example
of the use of conditions.  Something like:

(catch condition-code IN action)

where action is (if something (condition) (return ok))

plus a declaration of conditions.  Another way to help would be to point
me to a place where conditions are used in some ftpable code.

I need something to get started.

Thanks,
Bill
PS I am using MCL 2.02, and very much enjoying it compared to C, and even
compared to Modula-3, I think CL is a nice language.
PPS If anyone has any suggestions as to which lisp environment is nicest
for linux, I'm listening.  Eventually I would like to be able to program
under OS/2 as well (especially if Garnet became available.)
