Reminds me of early 00s phpBB MODs (which they allcapped to avoid confusion with moderators). It ended up this horrific syntax (http://web.archive.org/web/20041010114405/http://www.phpbb.com/kb/article.php?article_id=39 http://web.archive.org/web/20041010114405/http://www.phpbb.c... ) that functioned as both a bbcode forum post for manual instructions that didn't look too out of place for people to manually apply but also parseable for auto installers like easy mod. Then it turned into this XML file format in 3.0, which was similar in spirit but a more regular language made it less easy to screw up. XSL was used to make the "go edit it yourself" instructions version: http://web.archive.org/web/20160310004103/https://www.phpbb.com/mods/modx/sample-30-126.XML http://web.archive.org/web/20160310004103/https://www.phpbb.... It looks like they've finally ported to a real plugin system (https://www.phpbb.com/extensions/ https://www.phpbb.com/extensions/), but I had my fill of extend by patching in those days.
