-// Filename: Processor.cpp
-// =======================
-// Author: Benjamin Jurke
-// File history: 27.02.2002 - File created. Support for Intel and AMD processors
-// 05.03.2002 - Fixed the CPUID bug: On Pre-Pentium CPUs the CPUID
-// command is not available
-// - The CProcessor::WriteInfoTextFile function do not
-// longer use Win32 file functions (-> os independend)
-// - Optional include of the windows.h header which is
-// still need for CProcessor::GetCPUFrequency.
-// 06.03.2002 - My birthday (18th :-))
-// - Replaced the '\r\n' line endings in function
-// CProcessor::CPUInfoToText by '\n'
-// - Replaced unsigned __int64 by signed __int64 for
-// solving some compiler conversion problems
-// - Fixed a bug at family=6, model=6 (Celeron -> P2)
