| DXX-REBIRTH LICENSE |
| ==================== |
| The original Descent source release is copyright by Parallax and subject |
| to the Parallax license below. Contributions from the D1X/D2X ("DXX") |
| and D1X-Rebirth/D2X-Rebirth ("Rebirth") projects are copyright their |
| respective contributors. The DXX and Rebirth contributors grant you |
| permission to convey their work, with or without modifications, pursuant |
| to the terms of the GNU General Public License, version 3 ("GPLv3"). As |
| a special exception, in recognition of the restrictions imposed by the |
| original Parallax license, you are excused from GPLv3 requirements that |
| conflict with the restrictions of the original Parallax license, but |
| only to the extent that such excuse is required to prevent a conflict |
| between the terms of the original Parallax license and the GNU General |
| Public License v3. This special exception is an "Additional permission" |
| as defined by section 7 of the GNU General Public License v3. All |
| provisions of the GPLv3 that can be satisfied without violating the |
| original Parallax license must be satisfied to the greatest extent |
| possible without violating the original Parallax license. Failure to |
| satisfy any non-excused GPLv3 provision is expressly prohibited under |
| this license, and is therefore void and is handled pursuant to GPLv3 |
| section 8 "Termination.", exactly as would occur for a non-permitted |
| propagation or modification of a GPLv3 covered work that had no special |
| exceptions. |
| |
| For purposes of this document, "copyright by Parallax" shall include any |
| subsequent entities to which some or all of the Parallax copyrights were |
| transferred, without regard to how the transfer occurred. In the event |
| that you are permitted to convey the material originally copyright by |
| Parallax under terms other than the original Parallax license below, |
| whether due to a general relicensing by the appropriate copyright |
| holders, due to special permission from the appropriate copyright |
| holders, or any other circumstance, the contributions from the DXX and |
| Rebirth projects remain subject to the GNU General Public License, |
| version 3. The special exception described in the preceding paragraph |
| excuses only conflicts with the original Parallax license. If a |
| subsequent license to the Parallax work conflicts with the GPLv3 in any |
| way that the original Parallax license did not conflict, then such new |
| conflicts are not excused. As detailed in GPLv3 section 12 "No |
| Surrender of Others' Freedom.", if you cannot simultaneously satisfy the |
| non-excused terms of the GPLv3 and all other conditions imposed on you, |
| then you may not convey the GPLv3 covered work at all. |
| |
| Additionally, if you are permitted to convey the material originally |
| copyright by Parallax under terms other than the original Parallax |
| license, and such new permission allows you to comply with the GPLv3 to |
| a greater extent than the original Parallax license allowed, and you |
| convey the covered work or a portion thereof, then such conveyance must |
| comply with all GPLv3 terms which can be satisfied without violating the |
| permission under which you convey the material originally copyright by |
| Parallax. |
| |
| |
| See GPL-3.txt for further details on the GPLv3. |
