+
+RigelEngine [**-s** | **--skip-intro**] [**-d** | **--debug-mode**] [**--no-audio**] [**--play-demo**] [**-l** | **--play-level** *level-name*] [**--difficulty** *easy|medium|hard*] [**--player-pos** *x,y*] [*game-path*]
+
+DESCRIPTION
+===========
+
+**RigelEngine** is a modern reimplementation of the game Duke Nukem II,
+originally released in 1993 for MS-DOS by Apogee Software.
+
+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's user
+profile, so that you don't have to select it again next time.
+
+It's also possible to pass the path to the game files as argument on
+the command line.
+
+The only files actually used by RigelEngine are **NUKEM2.CMP** (the main
+data tile; required) and **NUKEM2.F1** through **NUKEM2.F5** (intro movie
+files; actually optional).
