      This is a POSIX binding for LuaJIT, Lua 5.1, 5.2 and 5.3;

      like most libraries it simply binds to C APIs on the

      underlying system, so it won't work on non-POSIX systems.

      However, it does try to detect the level of POSIX conformance

      of the underlying system and bind only available APIs.
