Subject: [PATCH] Initial implementation of view_related. The related_docs()
function is still a work in progress. I've been using
draft-ietf-dnsext-dnssec-protocol as a test case; related_docs() returns the
same 137 documents as the cgi code but some of the relationships are
different. Right now, the skip argument is ignored. - Legacy-Id: 246
