+This directory is intended to document the history of Supernova and
+provide documentation of how it became free software.
+
+Supernova was originally written by Scott Miller in the 1980s. Going
+off of the notices in the source code he began in 1985. The game was
+originally proprietary.
+
+Later, Scott Miller was one of the founders of Apogee Software, Ltd.
+in 1987 [0].
+
+According to the corporate timeline [1] Supernova was published in
+1987 before Apogee started and then released as freeware (but still
+proprietary) in 1998 [2]. In 2009 Apogee Software released the source
+code under the GPL [3].
+
+Based on the comments made in the announcement [3] and in the
+readme.txt that came with the game [4] it appears that they were
+putting it under the GPL as part of their process to throw the code
+over the wall to forget about. They even just added the part of it
+being GPLed underneath the previous text from where the game had been
+released as freeware in 1998.
+
+In reviewing the license headers in their release [5] there are
+copyright notices from Apogee Software so it appears that Scott Miller
+transferred his copyright to Apogee at some point. This make sense
+since he was one of the founders of the company and the game had been
+distributed as an Apogee program. Also, the license headers indicated
+it was specifically released under the GNU General Public License
+version 2 or any later version. I took advantage of that to upgrade it
+to the GNU General Public License version 3 or any later version. The
+modifications are licensed under the GNU Affero General Public License
+version 3 or any later version. This combination of GPLv3 or later and
+AGPLv3 or later is permitted under section 13 of each license.
