+2009-04-28 less CPU usage in command parsing, case insensitive config directives
+2009-04-28 GETSET command doc added
2009-04-28 GETSET tests
2009-04-28 GETSET implemented
2009-04-27 ability to specify a different file name for the DB
BEFORE REDIS 1.0.0-rc1
+- SMOVE _key1_ _key2_ _ele_. Pop an element form _key1_ and push (SADD or LPUSH) it nto _key2_.
- What happens if the saving child gets killed instead to end normally? Handle this.
- Make sinterstore / unionstore / sdiffstore returning the cardinality of the resulting set.
- Remove max number of args limit
