# Round Robin Software License 2.0.0

## Purpose

This license lets you use and share this software for free. You
can license your applications however you like, but you have
to contribute changes, additions, and other software that
builds on this software back on similar terms.

## Agreement

To receive this license, you have to agree to its rules. Those
rules are both obligations under that agreement and conditions
to your license. Don't do anything with this software against
any rule you can't or won't follow.

## Notices

Give the text of this license or a link to
<https://roundrobinlicense.com/2.0.0> to everyone who gets
a copy of any part of this software from you, along with
information making clear this license applies to the software.

## Copyleft

With two exceptions, [Prototypes](#prototypes) and
[Applications](#applications), contribute all changes and
additions you make to this software, as well as all software
that invokes this software's functionality. When in doubt,
contribute.

## Prototypes

You don't have to contribute any change, addition, or other
software that meets all these criteria:

1. You don't use it for more than thirty days.

2. You don't share it outside the team developing it, other
   than for non-production user testing.

3. You don't use it on behalf of anyone outside the team
   developing it.

## Applications

You don't have to contribute any software that only invokes
this software's functionality through the interfaces
this software exposes, unless it exposes so much of this
software's interfaces or functionality to users, programmers,
or other software that it becomes a practical substitute
for this software for any substantial portion of its use
cases. Interfaces exposed by this software include all the
interfaces this software provides users, programmers, or other
software to invoke its functionality, such as command line,
graphical, application programming, remote procedure call,
and inter-process communication interfaces.

## Contribute

To contribute software:

1. Publish all source code for the software in the preferred
   form for making changes through a freely accessible
   distribution system widely used for similar source code,
   so other contributors and users can find and copy it.

2. Make sure every part of the source code is available under
   this license, the Blue Oak Model License 1.0.0, or terms with
   substantially the same legal effect. You can include source
   code licensed by others under the MIT License, two-clause
   BSD License, BSD-2-Clause Plus Patent License, Apache License
   Version 2.0, or similar terms that give less certainty about
   patents, so long as the developers of the source code don't
   mention that patents apply or might apply to the software
   in code comments, documentation, or legal notices, and you
   aren't aware of any such patents yourself.

3. Take these steps within thirty days.

4. Note that this license doesn't let you change the license
   for this software. Follow [Notices](#notices).

## Excuse

You're excused for unknowingly breaking [Copyleft](#copyleft)
if you contribute as required, or stop doing anything
requiring this license, within thirty days of learning
you broke the rule. You're excused for unknowingly breaking
[Notices](#notices) if you take all practical steps to comply
within thirty days of learning you broke the rule.

## Copyright

Each contributor licenses you to do everything with this
software that would otherwise infringe their copyright in it.

## Patent

Each contributor licenses you to do everything with this
software that would otherwise infringe any patent claims they
can license or become able to license.

## Reliability

No contributor can revoke this license.

## No Liability

**_As far as the law allows, this software comes as is,
without any warranty or condition, and no contributor will
be liable to anyone for any damages related to this software
or this license, under any kind of legal claim._**
