					<h2>Port Scalar to C</h2>
					<p align="left">
						Most of Scalar was ported/reimplemented in upstream Git. Therefore, we can reduce maintenance burden by reimplementing what is left in <code>contrib/scalar/</code> in Microsoft's fork of Git.
					</p>
					<p align="left">
						Result: 4 additional files, ~800 lines of code
