License: 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.
