I have my own too. It is a Makefile that makes extensive use of the core utils (sed!) and xml2 and 2xml to be able to process HTML using the line-oriented tools in the core-utils. I also built a blog engine on top of git using sh scripts and the core-utils in git hooks (https://p4bl0.net/shebang/fugitive-readme.html https://p4bl0.net/shebang/fugitive-readme.html), but that was a long time ago and I don't use it anymore. It had a dozen users at some point and I even received a few contributions to the project. Fun times :).
