Hi Robert, thanks for your reply. Got it, no problem. I will adjust my
stuff accordingly.

It would really help a lot if the policy for the name of the system
and the corresponding .asd filename were spelled out in the ASDF
manual. As it stands, the manual doesn't say anything about
requirements for system-designator; there are incidental comments
suggesting using lowercase but not a specification or requirement. If
names are indeed restricted to lowercase letters, digits, and hyphens,
it would be great to say so.

On a separate topic, are there any restrictions on the names of
components? As it stands the manual says only that component names may
be either strings or symbols.  Mixed case component names appear to
work OK but that may be only fortuitous.

Thanks again, and best wishes.
