"server-cert.pem" and "private-key.pem" in `server-root-path', but
that seems to be the same as the --ssl command-line option. The ssl
server is created using the same code that "private/launch.ss" uses,
so it might be a good idea to abstract it into a separate file.
Also, `mime-types-path' defaults to "mime.types" in the
`server-root-path', but if the file is missing, then it uses
"mime.types" in the `default-configuration-table-path', which is a
sensible choice for just getting a server running.
