It seems to me that each server should have some kind of standard README note
so you can list servers with a one liner description of what they are for.
Now if we could agree on a standard name and format ...
Sorry if this has already been said before.
p.s. how about:
The file contains email like header:
Description: a few words only
Contact: John D. Smith <email@example.com
Then a multi line description of who runs it
and the aims and contents of this server.
