Thank you very much for sharing this tool.

I packaged this as a MSYS2 package for use in Git for Windows' SDKs. You can install it via

	pacman -Sy mingw-w64-x86_64-git-sizer

(obviously, if you are in a 32-bit SDK you want to replace x86_64 by i686)

Note: I am simply re-bundling the binaries you post to the GitHub
releases; The main purpose is to make it easier for users to include this
in their custom installers.

Second note: I briefly considered including this tool in Git for Windows, but it does increase the size of the installer by a full megabyte, and therefore I decided to keep it as SDK-only, optional package.

Thanks! Dscho
