func Int32SliceVar(p *[]int32, name string, value []int32, usage string) {
	CommandLine.VarP(newInt32SliceValue(value, p), name, "", usage)

Int32SliceVar defines a int32[] flag with specified name, default value, and usage string.
The argument p points to a int32[] variable in which to store the value of the flag.
