Plan 9 From User Space

Plan 9 From User Space is a port of the bulk of the Plan 9 software build environment to Unix. While the libraries make an attempt to play nice with the rest of the system (by using the Unix rules for printf verbs and Unix system headers, for example), this port tries to reproduce the Plan 9 build environment as faithfully as possible, providing u.h and libc.h, and blithely redefining tokens such as open, dup, and accept in order to provide implementations that better mimic the Plan 9 semantics. The result is a more complicated and less Unix-friendly environment, but Plan 9 programs can typically be compiled with little or no changes.
