commit c0483c7f851b2aa1933fb591eb0ca8f66b162022 Author: Nick Mathewson nickm@torproject.org Date: Mon Feb 10 22:41:52 2014 -0500
Remove options for configuring HS authorities.
(There is no longer meaningfully any such thing as a HS authority, since we stopped uploading or downloading v0 hs descriptors in 0.2.2.1-alpha.)
