================================================
This file is an agreement between Quviq AB ("Quviq"), Sven Hultins
Gata 9, Gothenburg, Sweden, and the committers to the github
repository in which the file appears ("the owner"). By placing this
file in a github repository, the owner agrees to the terms below.
The purpose of the agreement is to enable Quviq AB to provide a
continuous integration service to the owner, whereby the code in the
repository ("the source code") is tested using Quviq's test tools, and
the test results are made available on the web. The test results
include test output, generated test cases, and a copy of the source
code in the repository annotated with coverage information ("the test
results").
The owner agrees that Quviq may run the tests in the source code and
display the test results on the web, without obligation.
The owner warrants that running the tests in the source code and
displaying the test results on the web violates no laws, licences or other
agreements. In the event of such a violation, the owner accepts full
responsibility.
The owner warrants that the source code is not malicious, and will not
mount an attack on either Quviq's server or any other server--for
example by taking part in a denial of service attack, or by attempting
to send unsolicited emails.
The owner warrants that the source code does not attempt to reverse
engineer Quviq's code.
Quviq reserves the right to exclude repositories that break this
agreement from its continuous integration service.
Any dispute arising from the use of Quviq's service will be resolved
under Swedish law.

# How to run QuickCheck
In order to run QuickCheck you will need a license and to install QuickCheck.
## To Install QuickCheck
Download QuickCheck from http://quviq-licencer.com/downloads/eqc.zip
Unzip the file and CD Into the directory
as Root
```
erl
> eqc:install().
```
## Install your licence
As your user in Erlang
```
> eqc:registration("LICENCE ID").
```
## Running Properties
QuickCheck properties are in application directories `eqc`. There is a
`user_default.erl` file that has a few useful commands in it. To run
the QuickCheck properties from the Erlang shell type the command
`eqc()`.
## Running properties with Rebar3
run `rebar3 eqc` (Not yet working)

# Barrel platform
Barrel is a modern document-oriented database in Erlang focusing on data locality (put/match the data next to you) and
P2P.
Barrel must also be able to work in unreliable conditions were sometimes the quorum can't be achieved (because it is
working offline or in other conditions).
Because Barrel is built on an existing relatively small code base, it is possible to make radical changes as part of an
incremental process. Underpinning, all this work is efficient for small and large data systems — something rare among
database systems.
## Requirements
- OS supported: Linux, OSX, BSDs
- Erlang 19.2
## Prerequisites
This repository contains an [Erlang](https://www.erlang.org/) project packaged
with [rebar3](https://www.rebar3.org/). You need to have Erlang 19.1 and the latest version of
[rebar3](http://rebar3.org) installed to be able to create a release.
## Quickstart
$ make rel
$ ./_build/default/rel/barrel/bin/barrel start
## Building a release
Execute the following command line:
$ make rel
The generated release can be found in the folder `_build/prod/rel` .
> to build a development release, run the command line `make devrel` .
> Please note that this release can't be shipped outside of the current project,
> the release will be found in the folder `_build/default/rel`.
## Testing a release
To start a barrel http server:
$ ./_build/prod/rel/barrel/bin/barrel start
To stop it:
$ ./_build/prod/rel/barrel/bin/barrel stop
List of available commands:
$ ./_build/prod/rel/barrel/bin/barrel
You can consult the embedded [Swagger](http://swagger.io/) page at
http://localhost:7080/api-docs
## Packaging an autonomous tar file
This command create a tarbal including barrek, erlang and associated libs:
$ make tar
You can deploy the tarball wherever you want:
$ mkdir barrelprod
$ cd barrelprod
$ tar -xzf ../barrel-0.1.0.tar.gz
$ bin/barrel_http start
