Permission is hereby granted, free of charge, to any person obtaining a copy
of this Software and associated documentation files (the "Software"),
to use, reproduce, modify, prepare derivative works of, merge, publish,
distribute, sublicense, and/or sell copies of the Software, and to permit
persons to whom the Software is furnished to do so, provided that all
copyright notices, license terms, and conditions set forth in this License
are preserved and complied with.

### Definitions

For the purposes of this License:

"Software" means the Telemt software, including source code, documentation,
and any associated files distributed under this License.

"Contributor" means any person or entity that submits code, patches,
documentation, or other contributions to the Software that are accepted
into the Software by the maintainers.

"Contribution" means any work of authorship intentionally submitted
to the Software for inclusion in the Software.

"Modified Version" means any version of the Software that has been
changed, adapted, extended, or otherwise modified from the original
Software.

"Maintainers" means the individuals or entities responsible for
the official Telemt project and its releases.

#### 1 Attribution

Redistributions of the Software, in source or binary form, MUST RETAIN the
above copyright notice, this license text, and any existing attribution
notices.

#### 2 Modification Notice

If you modify the Software, you MUST clearly state that the Software has been
modified and include a brief description of the changes made.

Modified versions MUST NOT be presented as the original Telemt.

#### 3 Trademark and Branding

This license DOES NOT grant permission to use the name "Telemt", 
the Telemt logo, or any Telemt trademarks or branding.

Redistributed or modified versions of the Software MAY NOT use the Telemt
name in a way that suggests endorsement or official origin without explicit
permission from the Telemt maintainers.

Use of the name "Telemt" to describe a modified version of the Software
is permitted only if the modified version is clearly identified as a
modified or unofficial version.

Any distribution that could reasonably confuse users into believing that
the software is an official Telemt release is prohibited.

#### 4 Binary Distribution Transparency

If you distribute compiled binaries of the Software,
you are ENCOURAGED to provide access to the corresponding
source code and build instructions where reasonably possible.

This helps preserve transparency and allows recipients to verify the
integrity and reproducibility of distributed builds.

#### 5 Patent Grant and Defensive Termination Clause

Each contributor grants you a perpetual, worldwide, non-exclusive,
no-charge, royalty-free, irrevocable patent license to make, have made,
use, offer to sell, sell, import, and otherwise transfer the Software.

This patent license applies only to those patent claims necessarily
infringed by the contributor’s contribution alone or by combination of
their contribution with the Software.

If you initiate or participate in any patent litigation, including
cross-claims or counterclaims, alleging that the Software or any
contribution incorporated within the Software constitutes patent
infringement, then **all rights granted to you under this license shall
terminate immediately** as of the date such litigation is filed.

Additionally, if you initiate legal action alleging that the
Software itself infringes your patent or other intellectual
property rights, then all rights granted to you under this
license SHALL TERMINATE automatically.

#### 6 Contributions

Unless you explicitly state otherwise, any Contribution intentionally
submitted for inclusion in the Software shall be licensed under the terms
of this License.

By submitting a Contribution, you grant the Telemt maintainers and all
recipients of the Software the rights described in this License with
respect to that Contribution.

#### 7 Network Use Attribution

If the Software is used to provide a publicly accessible network service,
the operator of such service MUST provide attribution to Telemt in at least
one of the following locations:

- service documentation
- service description
- an "About" or similar informational page
- other user-visible materials reasonably associated with the service

Such attribution MUST NOT imply endorsement by the Telemt project or its
maintainers.

#### 8 Disclaimer of Warranty and Severability Clause

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 NONINFRINGEMENT.

IN NO EVENT SHALL THE AUTHORS OR COPYRIGHT HOLDERS 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

IF ANY PROVISION OF THIS LICENSE IS HELD TO BE INVALID OR UNENFORCEABLE,
SUCH PROVISION SHALL BE INTERPRETED TO REFLECT THE ORIGINAL INTENT
OF THE PARTIES AS CLOSELY AS POSSIBLE, AND THE REMAINING PROVISIONS
SHALL REMAIN IN FULL FORCE AND EFFECT
