RLC is a tool that performs reciprocal link checking automatically. Simply tell it where the remote Web pages you wish to monitor are, and the URLs of your links. It will then crawl the remote Web pages and give you feedback on the latest status (found, link not found, or page not found/network error). You may activate the checking as needed, or set up cron to carry out the checking once a week or so.
The Citations project is a simple extension that allows the user to select a text in a Web page and put it in a special bookmark file. Citations are stored in an RDF file and can be browsed in HTML view. You can save the selected text as a quoting in an internal database together with author and URL. Previously saved citations are presented in a table. Menui tems are added to the popup menu in Mozilla. Clicking a citation in the database opens the URL and highlights the text quoted.
MobileUserAgent is a PHP class which parses user agent identifier strings from browsers used by mobile devices to extract relevant information. It recognizes many of the current mobile user agent identifier strings and processes them to extract their basic constituent parts, the most important being the mobile device vendor and model.
