 %description
-This is a continuation of Mark Pilgrim's excellent chardet. Previously,
-two versions needed to be maintained: one that supported python 2.x
-and one that supported python 3.x. We've recently merged with
-Ian Cordasco's charade fork, so now we have one coherent version that
-works for Python 2.7+ and 3.4+.
