Formal specification for system exits

We support symbolic exit codes as described by sysexits(3) on FreeBSD systems.

Key concepts

Exit code When a process terminates it sends an exits code to its parent. The exit code 0 indicates a success, another exit code indicates an error. The precise value of the exit code can give a rough idea of the reason of the failure, without looking at the code of the program.
