interesting paragraph on why the builds are so small.

> You can download a 45 MiB tarball, unpack it, and you're done. You can even have multiple versions at the same time, no problem......Compare this to downloading Clang, which has 380 MiB Linux-distribution-specific tarballs. Zig's Linux tarballs are fully statically linked, and therefore work correctly on all Linux distributions. The size difference here comes because the Clang tarball ships with more utilities than a C compiler, as well as pre-compiled static libraries for both LLVM and Clang. Zig does not ship with any pre-compiled libraries; instead it ships with source code, and builds what it needs on-the-fly.
