Aintit.d 1.0.1 (Mac)

This simple package for OSX creates a wrapper which Apple's SystemStartup will execute upon system boot. It, in turn will serially execute any executables in a specific directory (/etc/rc.d). This was created to maintain some sense of order on my system, finding that Apple's recreation of the NeXT startup is not necessary for many mundane UNIX-centric tasks: the overhead of my little tool is less than the time involved creating the structure for Apple's initialization requirements.
