Subject: [PATCH] certificate-transparency: init at 2015-11-27 libevhtp: 1.2.10
 -> 1.2.11
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Package for certificate-transparency

This adds openssl support to libevent.  Libevent can be compiled without
openssl, in which case it just doesn't build the libevent_openssl
library.  However it seems simpler just to default to including openssl
support.

This bumps evhtp's version because 1.2.11 provides pkg-config
information which makes building certificate-transparency easier.

This has been tested with `doCheck = true;`.
