Program:

When args.length == 1, then the one element is args[0], not
args[1].
args[1] only exists when args.length >= 2.
To expand on that: argv[0] is what is passed to the process the D
program runs at in the system call it was spawned from (e.g.
execve), which usually corresponds to the program's name.
