 The value of `libkv` is not to duplicate the code for programs that should support multiple distributed K/V stores like the classic `Consul`/`etcd`/`zookeeper` trio.
 
 This document provides with general guidelines for users willing to support those backends with the same code using `libkv`.
 
 Please note that most of those workarounds are going to disappear in the future with `etcd` APIv3.

 Apiv3 is in the work for `etcd`, which removes this key/directory distinction, but until then you should follow these workarounds to make your `libkv` code work across backends.

 Will work on `Consul` and `zookeeper` but fail for `etcd`. This is because the first `Put` in the case of `etcd` will recursively create the directory hierarchy and `path/to/key` is now considered as a directory. Thus, values should always be stored on leaves if the support for the three backends is planned.

 The code above will work for the three backends but make sure to not try to store any value at that path as the call to `Put` will fail for `etcd` (you can only put at `path/to/key/foo`, `path/to/key/bar` for example).

 There is `Lock` mechanisms baked in the `coreos/etcd/client` for now. Instead, `libkv` has its own implementation of a `Lock` on top of `etcd`.

 The whole Lock process is highly dependent on the `delete`/`expire` events of `etcd`. So don't expect the key to be still there once the Lock is released.
 
-For example if the whole logic is to `Lock` a key and expect the value to still be there after it has been unlocked, it is not going to be cross-backend compatible with `Consul` and `zookeeper`. On the other end the `etcd` Lock can still be used to do Leader Election for example and still be cross-compatible with other backends.
