From 89e0728ba6057bfe45b635a42c36502e9edc8cb3 Mon Sep 17 00:00:00 2001 From: Gert Doering Date: Sat, 9 Apr 2011 18:16:21 +0200 Subject: Add more detailed explanation regarding the function of "--rdns-internal" MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit As agreed in last thursday's IRC meeting [1], I've added a comment to the code explaining "--rdns-internal". It's really very much an internal option, so it does not need to go to the man page.
