Triality is a php spider/crawler/search engine that doesn't use any database. Triality automatically searches up to 2 directories deep. Users can specify a specific path to perform the searches, and trinity will start digging down at that path instead of the main level. It can also be used as complete file listing for a website, and build the complete file tree. Also includes customizable results headers to make the output match your site. 2 versions available: one for linux, and one for linux/unix/etc. The latest version fixes 6 bugs, improved the speed, and gives file information for each search result.
