 * Implemented according to:

- AP-485 Intel(C) Processor Identification and the CPUID Instruction
        $(LINK http://www.intel.com/design/xeon/applnots/241618.htm)

- Intel(R) 64 and IA-32 Architectures Software Developer's Manual, Volume 2A: Instruction Set Reference, A-M

Example:
---
import std.cpuid;
import std.stdio;

void main()
{
    writefln(std.cpuid.toString());
}
