This works the same as C's exit() function; exits the program, passing a
certain error code to the shell. The shell expects the error code to be zero if
there was no error, or non-zero (any value you please) to indicate an error.
This value is used by other tools such as make; if make calls a program that
returns a non-zero error code, then make aborts the build.
