     "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.")
