+libcpuid is a small C library for x86 CPU detection and feature extraction. 
+Using it, you can:
+
+* get the processor vendor, model, brand string, code name
+* get information about CPU features such as: number of cores or logical CPUs, cache sizes, CPU clock
+* check if the processor implements a specific instruction set such as the SSE2, 3DNow!
+* execute the CPUID and RDTSC instructions (portably!)
+* and have this all in your commercial application, without getting into trouble.
+
+It works on Windows, Linux and Mac OS X, both 32-bit and 64-bit flavours. Compiler support 
+includes GCC and Microsoft Visual C++ (and compatible, e.g. Intel C++ compiler).

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
