Oh, the example is confusing, I just updated both the example and the
documentation.  The problem is that the example serves files, but not
directory listings.  So since you just requested "/" it said there was
nothing there.  If you pull down the latest version of the web-server
that example will now give a directory listing when "/" is requested.

Because none of the ws-* functions are commands, they are all functions
(meaning they don't have an interactive spec).  If you do `M-x
describe-function ws-TAB' you'll see a completion list.

This is because ws-* functions are all meant to be used from source
code, not called with M-x.  If you think any should have an interactive
spec added please let me know.

Thanks,
