-# cpuid
-Package cpuid provides information about the CPU running the current program.
-
-CPU features are detected on startup, and kept for fast access through the life of the application.
-Currently x86 / x64 (AMD64/i386) and ARM (ARM64) is supported, and no external C (cgo) code is used, which should make the library very easy to use.
-
-You can access the CPU information by accessing the shared CPU variable of the cpuid library.

-# private package
-
-In the "private" folder you can find an autogenerated version of the library you can include in your own packages.
-
-For this purpose all exports are removed, and functions and constants are lowercased.
-
-This is not a recommended way of using the library, but provided for convenience, if it is difficult for you to use external packages.
