+bufio
+=====
+
+This is a fork of the http://golang.org/pkg/bufio/ package. It adds `ReadN` method that allows reading next `n` bytes from the internal buffer without allocating intermediate buffer. This method works just like the [Buffer.Next](http://golang.org/pkg/bytes/#Buffer.Next) method, but has slightly different signature.

+- Redis 2.8 commands except QUIT, MONITOR, SLOWLOG and SYNC.
+- Pub/sub.
+- Transactions.
+- Pipelining.
+- Connection pool.
+- TLS connections.
+- Thread safety.
+- Timeouts.
+- Redis Sentinel.

+API docs: http://godoc.org/gopkg.in/redis.v2.
+Examples: http://godoc.org/gopkg.in/redis.v2#pkg-examples.
+
+Installation
+------------
+
+Install:
+
+    go get gopkg.in/redis.v2
+
+Look and feel
+-------------
+
+Some corner cases:
+
+    SORT list LIMIT 0 2 ASC
+    vals, err := client.Sort("list", redis.Sort{Offset: 0, Count: 2, Order: "ASC"}).Result()
