Sculpin is a PHP-based static website generator, ideal for powering websites that don't need dynamic DB-driven features or web-based administration. It's commonly used for blogging, but can be used for pretty much any marketing site you need, such as corporate websites, online portfolios, or even emergency downtime pages for when your WordPress site has been hacked ... (Kidding! Proper maintenance and security practices will make WordPress downtime a rarity.)
When running a website, you'll often want to reuse snippets of HTML. Many editors and IDEs have this functionality built in, but the problem with using editor snippets is maintainability. If you want to alter the snippet, you have to suss out every place it was used and manually edit it.
