+    (description
+     "HashLink (HL) is a virtual machine for the Haxe language.  It can run
+bytecode produced by the Haxe compiler, or converted to C by HL.  The HashLink runtime
+includes the following features:
+@itemize
+@item Fully compatible with the Haxe specification
+@item Support file I/O, regular expressions, network, etc.
+@item Unicode strings by default
+@item Mark-and-not-sweep Garbage Collector
+@item x86 and x86-64 HL/C compilation
+@item x86 and x86-64 HL/JIT compilation
+@end itemize
+
+While the standard HL runtime provides support for Haxe standard library,
+HashLink also provides several libraries that can optionally be used to build
+HL-specific applications.  This includes the FMT library for compression and
+image support and SDL for mouse, keyboard, and game controller support,
+OpenGL, and more.")
