 The `ncc` compiler is, at the time of this writing, incomplete in that it lacks some C features and the error messages need improvement. This compiler
 was implemented to serve as an example of how to write a compiler that targets UVM, and to write some library code to be used by other programs. Over
 time, the `ncc` compiler will be improved. Despite its limitations, it is still usable to write small programs. Contributions to it are welcome.

+The `spec` directory contains JSON files that represent a declarative list of system calls, constants and the permission system that UVM exposes
 to programs running on it. This is helpful for documentation purposes, or if you want to build a compiler that targets UVM. The directory also contains
