 Run [run.js](./run.js) to run each HTML minifier against each test and record the minified size results. This will also output the minified files in [min](./min) if inspection of minified outputs is necessary. [compare.sh](./compare.sh) is a useful script for viewing a character-by-character diff between the minified outputs of hyperbuild and html-minifier for a specific test. Pass the test's file name as the first argument.
