/**
 * For C/C++ applications, the argument count (argc) will always be at least
 * one, and the first element of the argument array (argv[0]) will contain
 * the program name. So if you type something like this:
 *
 *     myprogram one two three
 *
 * then argc will be four (4) and argv will contain "myprogram", "one",
 * "two" and "three".
 *
 * For Ruby applications, the size and contents of the argument array (ARGV)
 * just correspond to the application arguments; so if you type something like
 * this:
 *
 *     ruby myprogram.rb one two three
 *
 * then the ARGV will have three elements ("one", "two" and "three").
