The cdcat is a graphical (Qt based) multi-platform catalog program that scans the directories/drives you want and memorizes the filesystem (including the tags of MP3s) and stores it in a small file. The database is stored in a gzipped XML format, so you can hack it, or use it if necessary. Cdcat can store the contents of some specified files up to a size limit if you want (for example: *.nfo).
Classifieds Script allows you to start your own Web site to provide classified ads. Your classifieds site can have up to six different themes. It supports making money from listing fees and Google AdSense and banners. It has an optional WYSIWYG editor for ad posting. It provides an easy way to insert Google Analytics code or any other code for tracking. It supports using Google Maps to provide a map on site for each listing. Its notifier feature makes an HTML or plain text message appear on the home page after defined period of time. You can use this option for an opt-in form or any other message for visitors. RSS feeds can be provided for listings. The number of views for each listing is counted, as is the number of views from the category and search page.
