Parsing/Replacing Tidy/Linter/Stats

How to
This page has links to pages that display changes to linter counts on a weekly basis. The individual stats pages are generated as follows
 * Download the latest stats from https://tools.wmflabs.org/wikitext-deprecation/api
 * cd parsoid; tools/compare.linter.results.js $benchmark_stats_file $new_stats_file --wikify > stats.$date.wiki
 * The above step assumes you've been saving the stats files locally and have access to a previous date's stats file to use as the benchmark.
 * Edit the stats.$date.wiki file appropriately and upload to the wiki here.
