Neko 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. Learning and using Neko is very easy. 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 is a good way for language designers to focus on design and reuse a fast and well-designed runtime, as well as existing libraries for accessing filesystem, network, databases, XML, etc. It has a compiler and a virtual machine. The virtual machine is very lightweight and well optimized. The VM can be easily embedded into any application, and your libraries can be accessed using the C foreign function interface.
