The terms below govern Your rights to access and use this software.
By using the software in any way, You accept these terms in full.


1. DEFINITIONS

   "the Software" means this source code distribution and any
   binaries built from it, in whole or in part, including any
   Modifications.

   "You" means the individual or legal entity exercising rights
   under this license.

   "Internal Use" means use of the Software by You, Your employees,
   or Your contractors acting on Your behalf, including operating
   the Software on infrastructure deployed by You (including rented
   compute such as VPS or cloud instances You control) to support
   Your own products and operations.

   "Modifications" means any changes, additions, deletions, or
   derivative works that You make to the Software's source code.

   "Managed Service" means hosting the Software, or any substantial
   portion of its functionality, in a manner that allows third
   parties (other than Your employees or contractors acting on Your
   behalf) to use it through a network interface, or to take
   advantage of its functionality as a service or product offered
   to them. Your own customers receiving signed license keys from
   an instance of the Software You operate are NOT a Managed Service
   under this definition — that is the intended use case.


2. GRANT OF RIGHTS

   Subject to the restrictions in Section 3, the copyright holder
   grants You a non-exclusive, worldwide, royalty-free license to:

   (a) view, study, and audit the source code of the Software;

   (b) compile, install, and run the Software for Internal Use,
       including operating an instance as Your private licensing
       service to issue signed license keys for software products
       You sell or distribute;

   (c) make Modifications to the Software for the purposes of (a)
       and (b), provided that Modifications remain subject to this
       license.


3. RESTRICTIONS

   You may NOT, without prior written permission from the copyright
   holder:

   (a) distribute compiled binaries of the Software, or any
       derivative works in compiled form, to third parties, whether
       free of charge or for a fee;

   (b) provide the Software, or any substantial portion of its
       functionality, as a Managed Service;

   (c) sell, sublicense, lease, rent, or otherwise commercialize the
       Software itself (as distinguished from selling licenses to
       Your own software products through an instance of the
       Software You operate, which is expressly permitted under
       Section 2(b));

   (d) remove, alter, or obscure any copyright notices, license
       text, attribution lines, or this license file embedded in or
       accompanying the Software.

   Public source-code forks (for example, on GitHub) are permitted
   provided that the fork carries this license unchanged and does
   not enable, facilitate, or attempt to circumvent any of the
   prohibitions above.


4. CONTRIBUTIONS

   By submitting any contribution to the upstream project (code,
   documentation, designs, or other materials), You grant the
   copyright holder a perpetual, worldwide, non-exclusive,
   royalty-free, irrevocable license to use, reproduce, modify,
   relicense, distribute, and incorporate Your contribution as part
   of the Software or any future version of it, under the terms of
   this license or any later license the copyright holder adopts.
   You retain ownership of Your contribution; this Section grants
   a license-back, not an assignment of copyright.


5. NO WARRANTY

   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, TITLE, AND
   NON-INFRINGEMENT. IN NO EVENT SHALL THE 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 ITS USE OR OTHER DEALINGS IN
   THE SOFTWARE.


6. TERMINATION

   This license, and all rights granted to You under it, terminate
   automatically upon any breach of its terms. Upon termination,
   You must immediately cease all use of the Software and destroy
   or permanently delete all copies in Your possession or control.
   Sections 4 (Contributions), 5 (No Warranty), and 6 (Termination)
   survive any termination.


7. ENTIRE AGREEMENT

   This license constitutes the entire agreement between You and
   the copyright holder regarding the Software and supersedes any
   prior agreements, oral or written. No modification of this
   license is effective unless made in writing and signed by the
   copyright holder.
