for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with

5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of

incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the

work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing

and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this

Summary
=======
Cuesport is a simple pool of workers, meant mainly to be used with things like DB connections.
Use when poolboy's elaborate checkin/checkout seems to be overkill for your task.
Usage
-----
Suggested usage is to create your own wrapper module which wraps cuesport and provides
wrapper functions to hide pool's usage. Something in the lines of:
```erlang
-module(myproduct_redis).
-export([start_link/0, q/1, q/2]).
-define(POOL_NAME, myproduct_redis_pool).
%%%===================================================================
%%% API functions
%%%===================================================================
start_link() ->
PoolSize = get_config(redis_pool_size),
EredisOpts = get_config(redis_worker_config),
ChildMods = [eredis, eredis_client, eredis_parser],
ChildMFA = {eredis, start_link, EredisOpts},
cuesport:start_link(?POOL_NAME, PoolSize, ChildMods, ChildMFA).
q(Query) ->
eredis:q(cuesport:get_worker(?POOL_NAME), Query).
q(Query, Opts) ->
eredis:q(cuesport:get_worker(?POOL_NAME), Query, Opts).
```
Then add `myproduct_redis` to your supervision tree.
