retwis/Predis/Protocol/Text/TextCommandSerializer.php
antirez c58f935fdc Retwis ported to modern Redis data types.
The example (and related documentation at redis.io) was not updated for
5 years. Redis had no sorted sets and hashes when the original code was
written (!). An update was really needed.

We also use a modern PHP client now: Predis. A copy is shipped within
this repository to make life easier to newcomers trying Redis for the
first time via this example.
