Very stupid question about :module.

Hi

I know I should RTFM, but the wisdom of real people is better. Plus, I am lazy...

I would like to have a file depending on a "collection" of other files. I know I can use :module to do so, but how do I prevent the module from being cast into a directory? I.e., I have

bar.lisp zot.lisp foobar.lisp

I would like to say something like

(:module "barzot" :components ((:file "bar") (:file "zot")) (:file "foobar" :depends-on ("barzot")

How can I tell ASDF that there isn't any "barzot" folder? I know this must be a stupid question...

Thanks

Marco
