// 
// Some notes:
// (1) To build and run invoke the following:
//     `g++ main.cc -o main && ./main`
//     This program builds with GCC but not Clang. I think it's because the SIMD syntax for Clang and GCC is different
//     but I haven't confirmed this. Clang complains that `qN` is not a valid register. This would probably work fine
//     if I used the `arm_neon.h` intrinsics header.
// 
// (2) The codegen for Clang and GCC using the arm_neon header is somewhat different. It would be cool to see if one
//     version is significantly faster than the other.

  Upspin is an experimental project to build a framework for naming and sharing
  files and other data securely, uniformly, and globally: a global name system
  of sorts.
