     1.4 +On linux platforms, grok /proc/cpuinfo for the CPU/vendor info.
     1.5 +
     1.6 +Prob not suitable for upstream seeing as how it's 100% linux-specific
     1.7 +http://lists.gnu.org/archive/html/bug-coreutils/2005-09/msg00063.html
     1.8 +
     1.9 +Patch originally by Carlos E. Gorges <carlos@techlinux.com.br>, but 
    1.10 +heavily reworked to suck less.
    1.11 +
    1.12 +To add support for additional platforms, check out the show_cpuinfo()
    1.13 +func in the linux/arch/<ARCH>/ source tree of the kernel.
