Chinese University Released UNIX-like C++ OS

UnixLite, a small UNIX-like operating system written in C++, was released by Nanjing University of Aeronautics and Astronautics (NUAA) in China.

Accoding to UnixLite website, this lightweight system is more modular and easily understood because of its small size (the kernel is made up of about 20000 lines of code) and the object oriented programming using the c++ language.

Technical Features of UnixLite System:
Support paging and flat memory model, nearly same as linux
Implements about 80 posix compliant system call
Binary compatible with linux
Able to run bash/gcc, and some other common UNIX tools
Very rudimentary TCP/IP support, able to run a simple http server
Very small, about 20000 lines of code
Written in c++, highly modular and extensible
