+rigel-engine (Duke Nukem II reimplementation)
+
+RigelEngine is a reimplementation of the game Duke Nukem II,
+originally released by Apogee Software in 1993 for MS-DOS. RigelEngine
+works as a drop-in replacement for the original executable: It reads
+the game's data files and plays just like the original, but runs
+natively on modern operating systems and is written in modern C++
+code.
+
+If you're looking for the shareware data files, they're available here:
+https://archive.org/download/msdos_DUKE2_shareware/DUKE2.zip
+
+Compared to running the original in an emulator, RigelEngine offers
+many modern enhancements and usability improvements.
+
+The executable and man page are called "RigelEngine".

+.SH DESCRIPTION
+.sp
+\fBRigelEngine\fP is a modern reimplementation of the game Duke Nukem II,
+originally released in 1993 for MS\-DOS by Apogee Software.
+.sp
+In order to run RigelEngine, the game data from the original game is
+required. Both the shareware version and the registered version work.
+When launching RigelEngine for the first time, it will show a file
+browser UI and ask you to select the location of your Duke Nukem
+II installation. The chosen path will be stored in the game\(aqs user
+profile, so that you don\(aqt have to select it again next time.
+.sp
+It\(aqs also possible to pass the path to the game files as argument on
+the command line.
+.sp
+The only files actually used by RigelEngine are \fBNUKEM2.CMP\fP (the main
+data tile; required) and \fBNUKEM2.F1\fP through \fBNUKEM2.F5\fP (intro movie
+files; actually optional).

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
