Looks really nice!

I built an sdist out of the zfec repository and everything seem fine.
zfec also uses tox for running tests now. I will make a release soon
after testing with the 1.11.0b1 release.

I made a package and am happy to report that it all went well. We no
longer need a bunch of debian specific patches that we used to apply.

Another observation: My Debian machine which runs the 'testing' flavour
had the version 15.2.1 of Twisted and with that I get an error:

$ tahoe
Traceback (most recent call last):

  line 2610, in requires
    "%s has no such extra feature %r" % (self, ext)
pkg_resources.UnknownExtra: Twisted 15.2.1 has no such extra feature
'tls'

But if I upgrade the twisted package to 16.0.0 (which is currently in
Debian 'testing'), the error goes away and I have a working tahoe-lafs
system. I am a bit puzzled because on the OS-X 10.10.5, I see that
twisted version that comes with the system is 13.2.0 and that seem to
work fine. Perhaps it is something to do with the Debian packaging of
twisted which splits the package into multiple parts and perhaps some of
those parts got merged back into the main python-twisted package off
late, which I didn't notice. Perhaps the debian dependencies needs to be
adjusted to have the minimum of 16.0.0 so that those who are upgrading
tahoe but still having an older twisted installed will have a forced
upgrade of twisted as well... Apart from that, everything looks alright.
I will test more later today and tomorrow.

Cheers
