+// 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)
