0. The grant. Permission is granted, without fee, to any person who
   obtains a copy of this software and its documentation ("the software")
   to use, copy, run, and modify the software privately: for themselves,
   for their household, and on their own machines and home systems —
   including a private home-automation install and any seats or machines
   the person runs for their own purposes.

1. What counts as private use. Private use includes personal, household,
   hobby, educational, and research use, and evaluation or internal
   testing within a workplace, so long as the software is not used in
   the operation of a paid or revenue-generating product, service, or
   offering. A home is private use. A paid hosted product built on the
   software is not.

2. What the grant does not include. Without separate written permission
   from the author, you may not:
   - use the software in the operation of any commercial or
     revenue-generating product, service, or offering;
   - charge money (directly or bundled) for the software or for access
     to it;
   - distribute copies of the software — original or modified — or make
     it available to others as a download, bundle, or appliance;
   - offer the software, or a service built on it, to others.
   The author's own distribution of the software is unaffected by this
   section: the copyright holder's own rights are not limited by this
   license.

3. What you keep. You own your modifications. You may run your modified
   copy privately for as long as you like, and you are encouraged to
   send changes, bug reports, and fixes back to the author (issues and
   pull requests in the software's repository).

4. Other rights. The author may grant additional rights — commercial
   use, distribution, embedding — to anyone, case by case. Ask.

5. Notice. Keep this license and the copyright notice with any copy of
   the software, and inside any file where the original notice stood.

6. The usual disclaimers. THE SOFTWARE IS PROVIDED "AS IS", WITHOUT
   WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED
   TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR
   PURPOSE AND NON-INFRINGEMENT. IN NO EVENT SHALL THE AUTHOR OR
   COPYRIGHT HOLDER BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER LIABILITY,
   WHETHER IN AN ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING FROM,
   OUT OF OR IN CONNECTION WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS
   IN THE SOFTWARE.
