Integer flags accept 1234, 0664, 0x1234 and may be negative.
Boolean flags may be:

	1, 0, t, f, T, F, true, false, TRUE, FALSE, True, False

Duration flags accept any input valid for time.ParseDuration.

The default set of command-line flags is controlled by
top-level functions.  The [FlagSet] type allows one to define
independent sets of flags, such as to implement subcommands
