<p>Harvey is a new operating system. It’s most directly descended from Plan 9, the research operating system developed at Bell Labs as a successor to Unix. This influence spans from its distributed application architecture all the way down to much of its code. However, Harvey aims to be a more practical, general-purpose operating system, so it also uses ideas and code from other systems.</p>

<p>Harvey strives to provide an accessible development environment. The kernel is compact—less than 100,000 lines of code. You can build it with either GCC or LLVM, and run it under QEMU or real hardware. This makes it especially suitable for education and experimentation. It is a work in progress and the development team welcomes new contributors and ideas.</p>
