Coq au Vin is a blogging engine written in Chicken Scheme. It is designed to appeal to users who have basic Web development skills (i.e., who know HTML and CSS), are able to install their own server-side software, and would rather edit a template than press 105 buttons to customize their sites.
hulk is a usable in-browser HTML editor. Running $.hulk with some options will insert a pretty JSON editor into the div with the id "selector". You can then edit the document at your leisure, in text input boxes instead of as JSON. This makes it easy for programmers and non-technical people to collaborate on configuration. Hulk is also smart about detecting your input (if it's large, use a textarea, if it looks like a number, convert it to a number, etc.).
phpilelist is a file listing script that you can upload to a directory on your Web server. There's just one file to upload, and the script will list all files with extensions you specify and make them available for download. If you add, remove, or rename files, the listing will automatically update. If the directory contains a file named 'readme.txt', the script will show this file's contents above the download links.
