I hate to make any comments on this file but:

  * The original source is copyright 2011,2012,2013,2014 (which we typically illegally abbreviate as 2011-2014).
  * I'm not sure what the legality of saying "Twisted Matrix Laboratories" without a list of names is.  Perhaps it's totally fine but I don't think I'm actually qualified to say.  Another thing I'm sure I'm not qualified to say is that putting the names of the actual contributors in this file (like Twisted's LICENSE) would probably make things okay - me, glyph, wsanchez, and rwall seem to have been the only committers.
