    (description
     "The Neko programming language is a high-level dynamically typed
programming language.  It can be used as an embedded scripting language.  It
has been designed to provide a common runtime for several different languages.
You can easily extend the language with C libraries.  You can also write
generators from your own language to Neko and then use the Neko Runtime to
compile, run, and access existing libraries.

Neko has a compiler and a virtual machine.  The Virtual Machine is both very
lightweight and well optimized, so it can run very quickly.  The VM can be
easily embedded into any application and your libraries can be accessed using
the C foreign function interface.

You can use the compiler as standalone command line executable separate from
the VM, or as a Neko library to perform compile-and-run functions for
interactive languages.")

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.")
