The OSKit is a framework and set of modularized library code together with extensive documentation. Its goal is to make it easier for OS developers to create a new OS; to run user code directly on the hardware, including programming language runtimes; to port an existing OS to a platform supported by the OS kit; or to enhance an OS to support a wider range of devices, file system formats, or executable formats. For example, we have taken the freely available Kaffe JVM and ported it to the OSKit, giving us a simple Java interpreter with access to the BSD networking stack and linux device drivers running on ;bare hardware;: a ;Java Computer;.
