+    8086tiny is a tiny, open source (MIT), portable (little-endian hosts) Intel PC emulator, powerful enough to run DOS, Windows 3.0, Excel, MS Flight Simulator, AutoCAD, Lotus 1-2-3, and similar applications. 8086tiny emulates a "late 80's era" PC XT-type machine.
+    
+    8086tiny is based on an IOCCC 2013 winning entry. In fact that is the "unobfuscated" version :)
