+v0.6.3 (2011-01-01)
+  * New commands available in the Redis v2.2 profile (dev):
+      - Strings: SETRANGE, GETRANGE, SETBIT, GETBIT
+      - Lists  : BRPOPLPUSH
+
+  * The abstraction for MULTI/EXEC transactions has been dramatically improved 
+    by providing support for check-and-set (CAS) operations when using Redis >= 
+    2.2. Aborted transactions can also be optionally replayed in automatic up 
+    to a user-defined number of times, after which a Predis_AbortedMultiExec 
+    exception is thrown.
+
+v0.6.2 (2010-11-28)
+  * Minor internal improvements and clean ups.
+
+  * New commands available in the Redis v2.2 profile (dev):
+      - Strings: STRLEN
+      - Lists  : LINSERT, RPUSHX, LPUSHX
+      - ZSets  : ZREVRANGEBYSCORE
+      - Misc.  : PERSIST
+
+  * WATCH also accepts a single array parameter with the keys that should be 
+    monitored during a transaction.
+
+  * Improved the behaviour of Predis_MultiExecBlock in certain corner cases.
+
+  * Improved parameters checking for the SORT command.
+
+  * FIX: the STORE parameter for the SORT command didn't work correctly when 
+    using '0' as the target key (ISSUE #13).
+
+  * FIX: the methods for UNWATCH and DISCARD do not break anymore method
+    chaining with Predis\MultiExecBlock.
+
+v0.6.1 (2010-07-11)
+  * Minor internal improvements and clean ups.
+
+  * New commands available in the Redis v2.2 profile (dev):
+      - Misc.  : WATCH, UNWATCH
+
+  * Optional modifiers for ZRANGE, ZREVRANGE and ZRANGEBYSCORE queries are
+    supported using an associative array passed as the last argument of their
+    respective methods.
+
+  * The LIMIT modifier for ZRANGEBYSCORE can be specified using either:
+      - an indexed array: array($offset, $count)
+      - an associative array: array('offset' => $offset, 'count' => $count)
+
+  * The method Predis_Client::__construct() now accepts also instances of
+    Predis_ConnectionParameters.
+
+  * Predis_MultiExecBlock and Predis_PubSubContext now throw an exception
+    when trying to create their instances using a profile that does not
+    support the required Redis commands or when the client is connected to
+    a cluster of connections.
+
+  * Various improvements to Predis_MultiExecBlock:
+      - fixes and more consistent behaviour across various usage cases.
+      - support for WATCH and UNWATCH when using the current development
+        profile (Redis v2.2) and aborted transactions.
+
+  * New signature for Predis_Client::multiExec() which is now able to accept
+    an array of options for the underlying instance of Predis_MultiExecBlock.
+    Backwards compatibility with previous releases of Predis is ensured.
+
+  * New signature for Predis_Client::pipeline() which is now able to accept
+    an array of options for the underlying instance of Predis_CommandPipeline.
+    Backwards compatibility with previous releases of Predis is ensured.
+    The method Predis_Client::pipelineSafe() is to be considered deprecated.
+
+  * FIX: The WEIGHT modifier for ZUNIONSTORE and ZINTERSTORE was handled
+    incorrectly with more than two weights specified.
+
+v0.6.0 (2010-05-24)
+  * Switched to the new multi-bulk request protocol for all of the commands 
+    in the Redis 1.2 and Redis 2.0 profiles. Inline and bulk requests are now 
+    deprecated as they will be removed in future releases of Redis.
+
+  * The default server profile is "2.0" (targeting Redis 2.0.x). If you are 
+    using older versions of Redis, it is highly recommended that you specify 
+    which server profile the client should use (e.g. "1.2" when connecting 
+    to instances of Redis 1.2.x).
+
+  * Support for Redis 1.0 is now optional and it is provided by requiring 
+    'Predis_Compatibility.php' before creating an instance of Predis_Client.
+
+  * New commands added to the Redis 2.0 profile since Predis 0.5.1:
+      - Strings: SETEX, APPEND, SUBSTR
+      - ZSets  : ZCOUNT, ZRANK, ZUNIONSTORE, ZINTERSTORE, ZREMBYRANK, ZREVRANK
+      - Hashes : HSET, HSETNX, HMSET, HINCRBY, HGET, HMGET, HDEL, HEXISTS, 
+                 HLEN, HKEYS, HVALS, HGETALL
+      - PubSub : PUBLISH, SUBSCRIBE, UNSUBSCRIBE
+      - Misc.  : DISCARD, CONFIG
+
+  * Introduced client-level options with the new Predis_ClientOptions class. 
+    Options can be passed to Predis_Client::__construct in its second argument 
+    as an array or an instance of Predis_ClientOptions. For brevity's sake and 
+    compatibility with older versions, the constructor of Predis_Client still 
+    accepts an instance of Predis_RedisServerProfile in its second argument.
+    The currently supported client options are:
+      - profile [default: "2.0" as of Predis 0.6.0]
+        specifies which server profile to use when connecting to Redis. This 
+        option accepts an instance of Predis_RedisServerProfile or a string 
+        that indicates the target version.
+      - key_distribution [default: Predis_Distribution_HashRing]
+        specifies which key distribution strategy to use to distribute keys 
+        among the servers that compose a cluster. This option accepts an 
+        instance of Predis_Distribution_IDistributionStrategy so that users 
+        can implement their own key distribution strategy. Optionally, the new 
+        Predis_Distribution_KetamaPureRing class also provides a pure-PHP 
+        implementation of the same algorithm used by libketama.
+      - throw_on_error [default: TRUE]
+        server errors can optionally be handled "silently": instead of throwing 
+        an exception, the client returns an error response type.
+      - iterable_multibulk [EXPERIMENTAL - default: FALSE]
+        in addition to the classic way of fetching a whole multibulk reply 
+        into an array, the client can now optionally stream a multibulk reply 
+        down to the user code by using PHP iterators. It is just a little bit 
+        slower, but it can save a lot of memory in certain scenarios.
+
+  * New parameters for connections: 
+      - alias [default: not set]
+        every connection can now be identified by an alias that is useful to 
+        get a certain connection when connected to a cluster of Redis servers.
+      - weight [default: not set]
+        allows the client to balance the keys asymmetrically across multiple 
+        servers. This might be useful when you have servers with different 
+        amounts of memory and you want to distribute the load of your keys 
+        accordingly.
+      - connection_async [default: FALSE]
+        estabilish connections to servers in a non-blocking way, so that the 
+        client is not blocked while the underlying resource performs the actual 
+        connection.
+      - connection_persistent [default: FALSE]
+        the underlying connection resource is left open when a script ends its 
+        lifecycle. Persistent connections can lead to unpredictable or strange 
+        behaviours, so they should be used with extreme care.
+
+  * Introduced the Predis_Pipeline_IPipelineExecutor interface. Classes that 
+    implements this interface are used internally by the Predis_CommandPipeline 
+    class to change the behaviour of the pipeline when writing/reading commands 
+    from one or multiple servers. Here is the list of the default executors:
+      - Predis_Pipeline_StandardExecutor
+        Exceptions generated by server errors might be thrown depending on the 
+        options passed to the client (see "throw_on_error"). Instead, protocol 
+        or network errors always throw exceptions. This is the default executor 
+        for single and clustered connections and shares the same behaviour of 
+        Predis 0.5.x.
+      - Predis_Pipeline_SafeExecutor
+        Exceptions generated by server, protocol or network errors are not 
+        thrown, instead they are returned in the response array as instances of 
+        ResponseError or CommunicationException.
+      - Predis_Pipeline_SafeClusterExecutor
+        This executor shares the same behaviour of Predis_Pipeline_SafeExecutor 
+        but it is geared towards clustered connections.
+
+  * Support for PUBSUB is handled by the new Predis_PubSubContext class, which 
+    could also be used to build a callback dispatcher for PUBSUB scenarios.
+
+  * When connected to a cluster of connections, it is now possible to get a 
+    new Predis_Client instance for a single connection of the cluster by 
+    passing its alias/index to the new Predis_Client::getClientFor() method.
+
+  * CommandPipeline and MultiExecBlock return their instances when invoking 
+    commands, thus allowing method chaining in pipelines and multi-exec blocks.
+
+  * MultiExecBlock instances can handle the new DISCARD command.
+
+  * Connections now support float values for the connection_timeout parameter 
+    to express timeouts with a microsecond resolution.
+
+  * FIX: TCP connections now respect the read/write timeout parameter when 
+    reading the payload of server responses. Previously, stream_get_contents() 
+    was being used internally to read data from a connection but it looks like 
+    PHP does not honour the specified timeout for socket streams when inside 
+    this function.
+
+  * FIX: The GET parameter for the SORT command now accepts also multiple key 
+    patterns by passing an array of strings. (ISSUE #1).
+
+  * FIX: Replies to the DEL command return the number of elements deleted by 
+    the server and not 0 or 1 interpreted as a boolean response. (ISSUE #4).
+
+v0.5.1 (2010-01-23)
+  * RPOPLPUSH has been changed from bulk command to inline command in Redis
+    1.2.1, so ListPopLastPushHead now extends InlineCommand. The old RPOPLPUSH
+    behavior is still available via the ListPopLastPushHeadBulk class so that
+    you can override the server profile if you need the old (and uncorrect)
+    behaviour when connecting to a Redis 1.2.0 instance.
+
+  * Added missing support for BGREWRITEAOF for Redis >= 1.2.0
+
+  * Implemented a factory method for the RedisServerProfile class to ease the 
+    creation of new server profile instances based on a version string.
+
+v0.5.0 (2010-01-09)
+  * First versioned release of Predis

-v0.7.1 (2011-12-27)
-===============================================================================
-
-- The PEAR channel on PearHub has been deprecated in favour of `pear.nrk.io`.
-
-- Miscellaneous minor fixes.
-
-- Added transparent support for master / slave replication configurations where
-  write operations are performed on the master server and read operations are
-  routed to one of the slaves. Please refer to ISSUE #21 for a bit of history
-  and more details about replication support in Predis.
-
-- The `profile` client option now accepts a callable object used to initialize
-  a new instance of `Predis\Profiles\IServerProfile`.
-
-- Exposed a method for MULTI / EXEC contexts that adds the ability to execute
-  instances of Redis commands against transaction objects.
-
-
-v0.7.0 (2011-12-11)
-===============================================================================
-
-- Predis now adheres to the PSR-0 standard which means that there is no more a
-  single file holding all the classes of the library, but multiple files (one
-  for each class). You can use any PSR-0 compatible autoloader to load Predis
-  or just leverage the default one shipped with the library by requiring the
-  `Predis/Autoloader.php` and call `Predis\Autoloader::register()`.
-
-- The default server profile for Redis is now 2.4. The `dev` profile supports
-  all the features of Redis 2.6 (currently unstable) such as Lua scripting.
-
-- Support for long aliases (method names) for Redis commands has been dropped.
-
-- Redis 1.0 is no more supported. From now on Predis will use only the unified
-  protocol to serialize commands.
-
-- It is possible to prefix keys transparently on a client-level basis with the
-  new `prefix` client option.
-
-- An external connection factory is used to initialize new connection instances
-  and developers can now register their own connection classes using the new
-  `connections` client option.
-
-- It is possible to connect locally to Redis using UNIX domain sockets. Just
-  use `unix:///path/to/redis.sock` or a named array just like in the following
-  example: `array('scheme' => 'unix', 'path' => '/path/to/redis.sock');`.
-
-- If the `phpiredis` extension is loaded by PHP, it is now possible to use an
-  alternative connection class that leverages it to make Predis faster on many
-  cases, especially when dealing with big multibulk replies, with the the only
-  downside that persistent connections are not supported. Please refer to the
-  documentation to see how to activate this class using the new `connections`
-  client option.
-
-- Predis is capable to talk with Webdis, albeit with some limitations such as
-  the lack of pipelining and transactions, just by using the `http` scheme in
-  in the connection parameters. All is needed is PHP with the `curl` and the
-  `phpiredis` extensions loaded.
-
-- Way too many changes in the public API to make a list here, we just tried to
-  make all the Redis commands compatible with previous releases of v0.6 so that
-  you do not have to worry if you are simply using Predis as a client. Probably
-  the only breaking changes that should be mentioned here are:
-
-  - `throw_on_error` has been renamed to `throw_errors` and it is a connection
-    parameter instead of a client option, along with `iterable_multibulk`.
-
-  - `key_distribution` has been removed from the client options. To customize
-    the distribution strategy you must provide a callable object to the new
-    `cluster` client option to configure and then return a new instance of
-    `Predis\Network\IConnectionCluster`.
-
-  - `Predis\Client::create()` has been removed. Just use the constructor to set
-    up a new instance of `Predis\Client`.
-
-  - `Predis\Client::pipelineSafe()` was deprecated in Predis v0.6.1 and now has
-    finally removed. Use `Predis\Client::pipeline(array('safe' => true))`.
-
-  - `Predis\Client::rawCommand()` has been removed due to inconsistencies with
-    the underlying connection abstractions. You can still get the raw resource
-    out of a connection with `Predis\Network\IConnectionSingle::getResource()`
-    so that you can talk directly with Redis.
-
-- The `Predis\MultiBulkCommand` class has been merged into `Predis\Command` and
-  thus removed. Serialization of commands is now a competence of connections.
-
-- The `Predis\IConnection` interface has been splitted into two new interfaces:
-  `Predis\Network\IConnectionSingle` and `Predis\Network\IConnectionCluster`.
-
-- The constructor of `Predis\Client` now accepts more type of arguments such as
-  instances of `Predis\IConnectionParameters` and `Predis\Network\IConnection`.
-
-
-v0.6.6 (2011-04-01)
-===============================================================================
-
-- Switched to Redis 2.2 as the default server profile (there are no changes
-  that would break compatibility with previous releases). Long command names
-  are no more supported by default but if you need them you can still require
-  Predis_Compatibility.php to avoid breaking compatibility.
-
-- Added a `VERSION` constant to `Predis\Client`.
-
-- Some performance improvements for multibulk replies (parsing them is about
-  16% faster than the previous version). A few core classes have been heavily
-  optimized to reduce overhead when creating new instances.
-
-- Predis now uses by default a new protocol reader, more lightweight and
-  faster than the default handler-based one. Users can revert to the old
-  protocol reader with the 'reader' client option set to `composable`.
-  This client option can also accept custom reader classes implementing the
-  new `Predis\IResponseReader` interface.
-
-- Added support for connecting to Redis using UNIX domain sockets (ISSUE #25).
-
-- The `read_write_timeout` connection parameter can now be set to 0 or false
-  to disable read and write timeouts on connections. The old behaviour of -1
-  is still intact.
-
-- `ZUNIONSTORE` and `ZINTERSTORE` can accept an array to specify a list of the
-  source keys to be used to populate the destination key.
-
-- `MGET`, `SINTER`, `SUNION` and `SDIFF` can accept an array to specify a list
-  of keys. `SINTERSTORE`, `SUNIONSTORE` and `SDIFFSTORE` can also accept an
-  array to specify the list of source keys.
-
-- `SUBSCRIBE` and `PSUBSCRIBE` can accept a list of channels for subscription.
-
-- __FIX__: some client-side clean-ups for `MULTI/EXEC` were handled incorrectly
-  in a couple of corner cases (ISSUE #27).
-
-
-v0.6.5 (2011-02-12)
-===============================================================================
-
-- __FIX__: due to an untested internal change introduced in v0.6.4, a wrong
-  handling of bulk reads of zero-length values was producing protocol
-  desynchronization errors (ISSUE #20).
-
-
-v0.6.4 (2011-02-12)
-===============================================================================
-
-- Various performance improvements (15% ~ 25%) especially when dealing with
-  long multibulk replies or when using clustered connections.
-
-- Added the `on_retry` option to `Predis\MultiExecBlock` that can be used to
-  specify an external callback (or any callable object) that gets invoked
-  whenever a transaction is aborted by the server.
-
-- Added inline (p)subscribtion via options when initializing an instance of
-  `Predis\PubSubContext`.
-
-
-v0.6.3 (2011-01-01)
-===============================================================================
-
-- New commands available in the Redis v2.2 profile (dev):
-  - Strings: `SETRANGE`, `GETRANGE`, `SETBIT`, `GETBIT`
-  - Lists  : `BRPOPLPUSH`
-
-- The abstraction for `MULTI/EXEC` transactions has been dramatically improved
-  by providing support for check-and-set (CAS) operations when using Redis >=
-  2.2. Aborted transactions can also be optionally replayed in automatic up
-  to a user-defined number of times, after which a `Predis\AbortedMultiExec`
-  exception is thrown.
-
-
-v0.6.2 (2010-11-28)
-===============================================================================
-
-- Minor internal improvements and clean ups.
-
-- New commands available in the Redis v2.2 profile (dev):
-  - Strings: `STRLEN`
-  - Lists  : `LINSERT`, `RPUSHX`, `LPUSHX`
-  - ZSets  : `ZREVRANGEBYSCORE`
-  - Misc.  : `PERSIST`
-
-- WATCH also accepts a single array parameter with the keys that should be
-  monitored during a transaction.
-
-- Improved the behaviour of `Predis\MultiExecBlock` in certain corner cases.
-
-- Improved parameters checking for the SORT command.
-
-- __FIX__: the `STORE` parameter for the `SORT` command didn't work correctly
-  when using `0` as the target key (ISSUE #13).
-
-- __FIX__: the methods for `UNWATCH` and `DISCARD` do not break anymore method
-  chaining with `Predis\MultiExecBlock`.

-  Backwards compatibility with previous releases of Predis is ensured.
-
-- New signature for `Predis\Client::pipeline()` which is now able to accept
-  an array of options for the underlying instance of Predis\CommandPipeline.
-  Backwards compatibility with previous releases of Predis is ensured.
-  The method `Predis\Client::pipelineSafe()` is to be considered deprecated.
-
-- __FIX__: The `WEIGHT` modifier for `ZUNIONSTORE` and `ZINTERSTORE` was
-  handled incorrectly with more than two weights specified.
-
-
-v0.6.0 (2010-05-24)
-===============================================================================
-
-- Switched to the new multi-bulk request protocol for all of the commands
-  in the Redis 1.2 and Redis 2.0 profiles. Inline and bulk requests are now
-  deprecated as they will be removed in future releases of Redis.
-
-- The default server profile is `2.0` (targeting Redis 2.0.x). If you are

-
-- New commands added to the Redis 2.0 profile since Predis 0.5.1:
-  - Strings: `SETEX`, `APPEND`, `SUBSTR`
-  - ZSets  : `ZCOUNT`, `ZRANK`, `ZUNIONSTORE`, `ZINTERSTORE`, `ZREMBYRANK`,
-             `ZREVRANK`
-  - Hashes : `HSET`, `HSETNX`, `HMSET`, `HINCRBY`, `HGET`, `HMGET`, `HDEL`,
-             `HEXISTS`, `HLEN`, `HKEYS`, `HVALS`, `HGETALL`
-  - PubSub : `PUBLISH`, `SUBSCRIBE`, `UNSUBSCRIBE`
-  - Misc.  : `DISCARD`, `CONFIG`
-
-- Introduced client-level options with the new `Predis\ClientOptions` class.
-  Options can be passed to the constructor of `Predis\Client` in its second

-  an instance of `Predis\RedisServerProfile` in its second argument. The

-    profile to use when connecting to Redis. This option accepts an instance
-    of `Predis\RedisServerProfile` or a string that indicates the version.
-
-  - `key_distribution` [default: `Predis\Distribution\HashRing`]: specifies
-    which key distribution strategy to use to distribute keys among the
-    servers that compose a cluster. This option accepts an instance of
-    `Predis\Distribution\IDistributionStrategy` so that users can implement
-    their own key distribution strategy. `Predis\Distribution\KetamaPureRing`
-    is an alternative distribution strategy providing a pure-PHP implementation
-    of the same algorithm used by libketama.
-
-  - `throw_on_error` [default: `TRUE`]: server errors can optionally be handled
-    "silently": instead of throwing an exception, the client returns an error
-    response type.
-
-  - `iterable_multibulk` [EXPERIMENTAL - default: `FALSE`]: in addition to the

-    can now optionally stream a multibulk reply down to the user code by using
-    PHP iterators. It is just a little bit slower, but it can save a lot of

-    might be thrown depending on the options passed to the client (see the
-    `throw_on_error` client option). Instead, protocol or network errors always
-    throw exceptions. This is the default executor for single and clustered
-    connections and shares the same behaviour of Predis 0.5.x.
-  - `Predis\Pipeline\SafeExecutor`: exceptions generated by server, protocol
-    or network errors are not thrown but returned in the response array as
-    instances of `Predis\ResponseError` or `Predis\CommunicationException`.
-  - `Predis\Pipeline\SafeClusterExecutor`: this executor shares the same
-    behaviour of `Predis\Pipeline\SafeExecutor` but it is geared towards
-    clustered connections.
-
-- Support for PUB/SUB is handled by the new `Predis\PubSubContext` class, which
-  could also be used to build a callback dispatcher for PUB/SUB scenarios.
-
-- When connected to a cluster of connections, it is now possible to get a
-  new `Predis\Client` instance for a single connection of the cluster by
-  passing its alias/index to the new `Predis\Client::getClientFor()` method.
-
-- `Predis\CommandPipeline` and `Predis\MultiExecBlock` return their instances
-  when invokink commands, thus allowing method chaining in pipelines and
-  multi-exec blocks.
-
-- `Predis\MultiExecBlock` can handle the new `DISCARD` command.
-
-- Connections now support float values for the `connection_timeout` parameter
-  to express timeouts with a microsecond resolution.
-
-- __FIX__: TCP connections now respect the read/write timeout parameter when
-  reading the payload of server responses. Previously, `stream_get_contents()`
-  was being used internally to read data from a connection but it looks like
-  PHP does not honour the specified timeout for socket streams when inside
-  this function.
-
-- __FIX__: The `GET` parameter for the `SORT` command now accepts also multiple
-  key patterns by passing an array of strings. (ISSUE #1).
-
-* __FIX__: Replies to the `DEL` command return the number of elements deleted
-  by the server and not 0 or 1 interpreted as a boolean response. (ISSUE #4).
-
-
-v0.5.1 (2010-01-23)
-===============================================================================
-
-* `RPOPLPUSH` has been changed from bulk command to inline command in Redis
-  1.2.1, so `ListPopLastPushHead` now extends `InlineCommand`. The old behavior
-  is still available via the `ListPopLastPushHeadBulk` class so that you can
-  override the server profile if you need the old (and uncorrect) behaviour
-  when connecting to a Redis 1.2.0 instance.
-
-* Added missing support for `BGREWRITEAOF` for Redis >= 1.2.0.
-
-* Implemented a factory method for the `RedisServerProfile` class to ease the
-  creation of new server profile instances based on a version string.

-# Some frequently asked questions about the performances of Predis #
-____________________________________________
-
-
-### Predis is a pure-PHP implementation: it can not be fast enough! ###
-
-It really depends, but most of the times the answer is: _yes, it is fast enough_. I will give you
-a couple of easy numbers using a single Predis client with PHP 5.3.5 (custom build) and Redis 2.2
-(localhost) under Ubuntu 11.04 (running on a Intel Q6600):
-
-    19600 SET/sec using 12 bytes for both key and value
-    18900 GET/sec while retrieving the very same values
-    0.200 seconds to fetch 30000 keys using _KEYS *_.
-
-How does it compare with a nice C-based extension such as [__phpredis__](http://github.com/nicolasff/phpredis)?
-
-    30500 SET/sec using 12 bytes for both key and value
-    31000 GET/sec while retrieving the very same values
-    0.030 seconds to fetch 30000 keys using "KEYS *"".
-
-Wow, __phpredis__ looks so much faster! Well we are comparing a C extension with a pure-PHP library so
-lower numbers are quite expected, but there is a fundamental flaw in them: is this really how you are
-going to use Redis in your application? Are you really going to send thousands of commands in a for-loop
-for each page request using a single client instance? If so, well I guess you are probably doing something
-wrong. Also, if you need to SET or GET multiple keys you should definitely use commands such as MSET and
-MGET. You can also use pipelining to get more performances when this technique can be used.
-
-There is one more thing. We have tested the overhead of Predis by connecting on a localhost instance of
-Redis, but how these numbers change when we hit the network by connecting to instances of Redis that
-reside on other servers?
-
-    Using Predis:
-    3600 SET/sec using 12 bytes for both key and value
-    3600 GET/sec while retrieving the very same values
-    0.210 seconds to fetch 30000 keys using "KEYS *".
-
-    Using phpredis:
-    4000 SET/sec using 12 bytes for both key and value
-    4000 GET/sec while retrieving the very same values
-    0.051 seconds to fetch 30000 keys using "KEYS *".
-
-There you go, you get almost the same average numbers and the reason is quite simple: network latency
-is a real performance killer and you cannot do (almost) anything about that. As a disclaimer, please
-remember that we are measuring the overhead of client libraries implementations and the effects of the
-network round-trip time, we are not really measuring how fast Redis is. Redis shines the best with
-thousands of concurrent clients doing requests! Also, actual performances should be measured according
-to how your application will use Redis.
-
-
-### I am convinced, but performances for multi-bulk replies (e.g. _KEYS *_) are still worse ###
-
-Fair enough, but there is actually an option for you if you need even more speed and it consists on
-installing __[phpiredis](http://github.com/seppo0010/phpiredis)__ (note the additional _i_ in the
-name) and let Predis using it. __phpiredis__ is a C-based extension that wraps __hiredis__ (the
-official Redis C client library) with a thin layer that exposes its features to PHP. You will now
-get the benefits of a faster protocol parser just by adding a single line of code in your application:
-
-    $client = new Predis\Client('tcp://127.0.0.1', array(
-        'connections' => array('tcp' => 'Predis\Network\PhpiredisConnection')
-    ));
-
-As simple as it is, nothing will really change in the way you use the library in your application. So,
-how fast is it now? There are not much improvements for inline or short bulk replies (e.g. _SET_ or
-_GET_), but the speed for parsing multi-bulk replies is now on par with phpredis:
-
-    Using Predis with a phpiredis-based connection to fetch 30000 keys using _KEYS *_:
-
-    0.031 seconds from a local Redis instance
-    0.058 seconds from a remote Redis instance
-
-
-### If I need to install a C extension to get better performances, why not using phpredis? ###
-
-Good question. Generically speaking, if you need absolute uber-speed using localhost instances of Redis
-and you do not care about abstractions built around some Redis features such as MULTI / EXEC, or if you
-do not need any kind of extensibility or guaranteed backwards compatibility with different versions of
-Redis (Predis currently supports from 1.2 up to 2.2, and even the current development version), then
-using __phpredis__ can make sense for you. Otherwise, Predis is for you. Using __phpiredis__ gives you
-a nice speed bump, but it is not mandatory.

-# Some frequently asked questions about Predis #
-____________________________________________
-
-
-### What is the point of Predis? ###
-
-The main point of Predis is about offering a highly customizable client for Redis that can be easily
-extended by developers while still being reasonabily fast. With Predis you can swap almost any class
-used internally with your own custom implementation: you can build connection classes, or new
-distribution strategies for client-side sharding, or class handlers to replace existing commands or
-add new ones. All of this can be achieved without messing with the source code of the library and
-directly in your own application. Given the fast pace at which Redis is developed and adds new
-features, this can be a great asset that allows you to add new and still missing features or commands,
-or change the behaviour of the library without the need to break your dependencies in production code
-(well, at least to some degree).
-
-
-### How about performances? ###
-
-Please refer to the dedicated __FAQ.PERFORMANCES__ file.
-
-
-### Why PHP 5.3? ###
-
-Seriously, are you still using PHP 5.2 to build new applications? I assume that if you are throwing Redis
-in the mix, then you are probably coding something new after all. PHP 5.3 is faster, less memory hungry
-and has a few nice features such as namespaces and closures (kind of). More importantly, PHP 5.2 is not
-even officially supported anymore (aside from security patches). PHP 5.3 is not the future of PHP, but
-its current present. Furthermore, most of the existing frameworks out there are also making the switch
-with their respective new major versions. If you still insist on using PHP 5.2, you can get any recent
-backported release of Predis 0.6.x, or just use a different library.
-
-
-### Why so many files for just one library? ###
-
-Before v0.7, Predis used the one-big-file approach to distribute the library. As much as you prefer having
-just one file for everything, this kind of solution is actually not that good. Predis now complies with the
-[PSR-0](http://groups.google.com/group/php-standards/web/psr-0-final-proposal) standard to play nice with
-the major recent frameworks and libraries, so it needs an autoloader function to be defined. If you still
-want to have just one file grouping all the classes for whatever reason, then the __bin/create-single-file.php__
-script in the repository can generate it for you. There is also the __bin/create-phar.php__ script that
-generates a single [Phar archive](http://www.php.net/manual/en/intro.phar.php) of the whole library.
-
-
-### Does Predis support UNIX domain sockets and persistent connections? ###
-
-Yes. Obviously, persistent connections actually work when using PHP configured as a persistent process that
-gets recycled between requests (see [PHP-FPM](http://php-fpm.org/)).
-
-
-### Does Predis support transparent (de)serialization of values? ###
-
-No, and it will not ever do that for you by default. The reason behind this decision is that serialization
-is usually something that developers prefer to customize depending on their needs and can not be easily
-generalized when using Redis because of the many possible access patterns for the data. This does not
-mean that it is impossible to have such a feature, you can leverage Predis' extensibility to define your
-own serialization-aware commands. See [here](http://github.com/nrk/predis/issues/29#issuecomment-1202624)
-for more details on how to implement such a feature with a practical example.

+# Predis #
+
+## About ##
+
+Predis is a flexible and feature-complete PHP client library for the Redis key-value 
+database. It currently comes in two flavors:
+
+ - the mainline client library, which targets PHP 5.3.x and leverages a lot of the 
+   features introduced in this new version of the PHP interpreter.
+ - a backport to PHP 5.2.x for those who can not upgrade their environment yet 
+   (it admittedly has a lower priority compared to the mainline library, although we 
+   try to keep the two versions aligned as much as possible).
+
+Please refer to the TODO file to see which issues are still pending and what is due 
+to be implemented soon in Predis.
+
+
+## Main features ##
+
+- Full support for Redis 2.0. Different versions of Redis are supported via server profiles.
+- Client-side sharding (support for consistent hashing and custom distribution strategies).
+- Command pipelining on single and multiple connections (transparent).
+- Abstraction for Redis transactions (>= 2.0) with support for CAS operations (>= 2.2).
+- Lazy connections (connections to Redis instances are only established just in time).
+- Flexible system to define and register your own set of commands to a client instance.
+
+
+## Quick examples ##
+
+See the [official wiki](http://wiki.github.com/nrk/predis) of the project for a more 
+complete coverage of all the features available in Predis.
+
+### Connecting to a local instance of Redis ###
+
+You don't have to specify a tcp host and port when connecting to Redis instances 
+running on the localhost on the default port:
+
+    $redis = new Predis_Client();
+    $redis->set('library', 'predis');
+    $value = $redis->get('library');
+
+
+### Pipelining multiple commands to a remote instance of Redis ##
+
+Pipelining helps with performances when there is the need to issue many commands 
+to a server in one go:
+
+    $redis = new Predis_Client('redis://10.0.0.1:6379/');
+    $pipe  = $redis->pipeline();
+    $pipe->ping();
+    $pipe->incrby('counter', 10);
+    $pipe->incrby('counter', 30);
+    $pipe->get('counter');
+    $replies = $pipe->execute();
+
+
+### Pipelining multiple commands to multiple instances of Redis (sharding) ##
+
+Predis supports data sharding using consistent-hashing on keys on the client side. 
+Furthermore, a pipeline can be initialized on a cluster of redis instances in the 
+same exact way they are created on single connection. Sharding is still transparent 
+to the user:
+
+    $redis = new Predis_Client(array(
+        array('host' => '10.0.0.1', 'port' => 6379),
+        array('host' => '10.0.0.2', 'port' => 6379)
+    ));
+
+    $pipe = $redis->pipeline();
+    for ($i = 0; $i < 1000; $i++) {
+        $pipe->set("key:$i", str_pad($i, 4, '0', 0));
+        $pipe->get("key:$i");
+    }
+    $replies = $pipe->flushPipeline();
+
+
+### Definition and runtime registration of new commands on the client ###
+
+Let's suppose Redis just added the support for a brand new feature associated 
+with a new command. If you want to start using the above mentioned new feature 
+right away without messing with Predis source code or waiting for it to find 
+its way into a stable Predis release, then you can start off by creating a new 
+class that matches the command type and its behaviour and then bind it to a 
+client instance at runtime. Actually, it is easier done than said:
+
+    class BrandNewRedisCommand extends Predis_MultiBulkCommand {
+        public function getCommandId() { return 'NEWCMD'; }
+    }
+
+    $redis = new Predis_Client();
+    $redis->getProfile()->registerCommand('BrandNewRedisCommand', 'newcmd');
+    $redis->newcmd();
+
+
+## Development ##
+
+Predis is fully backed up by a test suite which tries to cover all the aspects of the 
+client library and the interaction of every single command with a Redis server. If you 
+want to work on Predis, it is highly recommended that you first run the test suite to 
+be sure that everything is OK, and report strange behaviours or bugs.
+
+The recommended way to contribute to Predis is to fork the project on GitHub, fix or 
+add features on your newly created repository and then submit issues on the Predis 
+issue tracker with a link to your repository. Obviously, you can use any other Git 
+hosting provider of you preference. Diff patches will be accepted too, even though 
+they are not the preferred way to contribute to Predis.
+
+When modifying Predis please be sure that no warnings or notices are emitted by PHP 
+by running the interpreter in your development environment with the "error_reporting"
+variable set to E_ALL | E_STRICT.
+
+
+## Dependencies ##
+
+- PHP >= 5.3.0 (for the mainline client library)
+- PHP >= 5.2.6 (for the backported client library)
+- PHPUnit (needed to run the test suite)

-## How to use Predis ##
-
-Predis is available on [Packagist](http://packagist.org/packages/predis/predis) for an easy installation
-using [Composer](http://packagist.org/about-composer). Composer helps you manage dependencies for your
-projects and libraries without much hassle which makes it the preferred way to get up and running with
-new applications. Alternatively, the library is available on our [own PEAR channel](http://pear.nrk.io)
-for a more traditional installation via PEAR. Zip and tar.gz archives are also downloadable from GitHub
-by browsing the list of [tagged releases](http://github.com/nrk/predis/tags).
-
-
-### Loading the library ###
-
-To automatically load all of its files, Predis relies on the autoloading features of PHP and complies
-with the [PSR-0 standard](http://github.com/php-fig/fig-standards/blob/master/accepted/PSR-0.md) for
-interoperability with most of the major frameworks and libraries. Everything is transparently handled
-for you when installing the library using Composer, but you can also leverage its own autoloader class
-if you are going to use it in a project or script without any PSR-0 compliant autoloading facility:
-
-``` php
-<?php
-// prepend a base path if Predis is not present in your "include_path".
-require 'Predis/Autoloader.php';
-
-Predis\Autoloader::register();
-```
-
-You can create a single [Phar](http://www.php.net/manual/en/intro.phar.php) archive from the repository
-just by launching the `bin/create-phar.php` executable script. The generated Phar archive ships with a
-stub defining an autoloader function for Predis, so you just need to require the Phar to be able to use
-the library.
-
-Alternatively you can generate a single PHP file that holds every class, just like older versions of
-Predis, using the `bin/create-single-file.php` executable script. In this way you can load Predis in your
-scripts simply by using functions such as `require` and `include`, but this practice is not encouraged.
-
-
-### Connecting to a local instance of Redis ###
-
-When connecting to local instance of Redis (`127.0.0.1` on port `6379`), you do not have to specify any
-additional parameter to create a new client instance:
-
-``` php
-<?php
-$redis = new Predis\Client();
-$redis->set('foo', 'bar');
-$value = $redis->get('foo');
-```
-
-However you can use an URI string or a named array to specify the needed connection parameters:
-
-``` php
-<?php
-$redis = new Predis\Client('tcp://10.0.0.1:6379');
-
-// is equivalent to:
-
-$redis = new Predis\Client(array(
-    'scheme' => 'tcp',
-    'host'   => '10.0.0.1',
-    'port'   => 6379,
-));
-```
-
-
-### Pipelining multiple commands to multiple instances of Redis with client-side sharding ###
-
-Pipelining helps with performances when there is the need to send many commands to a server in one go.
-Furthermore, pipelining works transparently even on aggregated connections. To achieve this, Predis
-supports client-side sharding using consistent-hashing on keys while clustered connections are supported
-natively by the client class.
-
-``` php
-<?php
-$redis = new Predis\Client(array(
-    array('host' => '10.0.0.1', 'port' => 6379),
-    array('host' => '10.0.0.2', 'port' => 6379)
-));
-
-$replies = $redis->pipeline(function($pipe) {
-    for ($i = 0; $i < 1000; $i++) {
-        $pipe->set("key:$i", str_pad($i, 4, '0', 0));
-        $pipe->get("key:$i");
-    }
-});
-```
-
-
-### Overriding standard connection classes with custom ones ###
-
-Predis allows developers to create new connection classes to add support for new protocols or override
-the existing ones and provide a different implementation compared to the default classes. This can be
-obtained by subclassing the `Predis\Network\IConnectionSingle` interface.
-
-``` php
-<?php
-class MyConnectionClass implements Predis\Network\IConnectionSingle
-{
-    // implementation goes here
-}
-
-// Let Predis automatically use your own class to handle connections identified by the tcp scheme.
-$client = new Predis\Client('tcp://127.0.0.1', array(
-    'connections' => array('tcp' => 'MyConnectionClass')
-));
-```
-
-The classes contained in the `Predis\Network` namespace give you a better insight with actual code on
-how to create new connection classes.
-
-
-### Defining and registering new commands on the client at runtime ###
-
-Let's suppose Redis just added the support for a brand new feature associated with a new command. If
-you want to start using the above mentioned new feature right away without messing with Predis source
-code or waiting for it to find its way into a stable Predis release, then you can start off by creating
-a new class that matches the command type and its behaviour and then bind it to a client instance at
-runtime. Actually, it is easier done than said:
-
-``` php
-<?php
-class BrandNewRedisCommand extends Predis\Commands\Command
-{
-    public function getId()
-    {
-        return 'NEWCMD';
-    }
-}
-
-$redis = new Predis\Client();
-$redis->getProfile()->defineCommand('newcmd', 'BrandNewRedisCommand');
-$redis->newcmd();
-```
-
-
-## Test suite ##
-
-__ATTENTION__: Do not ever run the test suite shipped with Predis against instances of Redis running in
-production environments or containing data you are interested in!
-
-Predis has a comprehensive test suite covering every aspect of the library. The suite performs integration
-tests against a running instance of Redis (>= 2.4.0 is required) to verify the correct behaviour of the
-implementation of each command and automatically skips commands not defined in the selected version of
-Redis. If you do not have Redis up and running, integration tests can be disabled. By default, the test
-suite is configured to execute integration tests using the server profile for Redis v2.4 (which is the
-current stable version of Redis). You can optionally run the suite against a Redis instance built from
-the `unstable` branch with the development profile by changing the `REDIS_SERVER_VERSION` to `dev` in
-the `phpunit.xml` file. More details about testing Predis are available in `tests/README.md`.
-
-Predis uses Travis CI for continuous integration. You can find the results of the test suite and the build
-history [on its project page](http://travis-ci.org/nrk/predis).
-
-
-## Contributing ##
-
-If you want to work on Predis, it is highly recommended that you first run the test suite in order to
-check that everything is OK, and report strange behaviours or bugs. When modifying Predis please make
-sure that no warnings or notices are emitted by PHP by running the interpreter in your development
-environment with the `error_reporting` variable set to `E_ALL | E_STRICT`.
-
-The recommended way to contribute to Predis is to fork the project on GitHub, create new topic branches
-on your newly created repository to fix or add features (possibly with tests covering your modifications)
-and then open a new pull request with a description of the applied changes. Obviously you can use any
-other Git hosting provider of your preference.

-//
-//   $ ./bin/generate-command-test.php --class=StringSet
-//
-// Here is a list of optional arguments:

-// --realm: each command has its own realm (commands that operate on strings,
-// lists, sets and such) but while this realm is usually inferred from the name
-// of the specified class, sometimes it can be useful to override it with a
-// custom one.
-//
-// --output: write the generated test case to the specified path instead of
-// the default one.
-//
-// --overwrite: pre-existing test files are not overwritten unless this option
-// is explicitly specified.
