14       $domain = trim_domain($fqdn)

20               "www.foo.com" => "foo.com"
21               "www.foo.co.uk" => "foo.co.uk"

23       $ok = is_domain_valid($dom)
24           Return 1 if the domain is valid, "undef" otherwise.  A valid domain
25           (a) does not contain whitespace, (b) contains at least one dot, and
26           (c) uses a valid TLD or ccTLD.
