Do is an intelligent launcher tool that makes performing common tasks on your computer simple and efficient. Do not only allows you to search for items in your desktop environment (e.g. applications, contacts, bookmarks, files, music), it also allows you to specify actions to perform on search results (e.g. Run, Open, Email, Chat, Play, etc.) and it allows you to quickly search for many items present in your GNOME desktop environment (applications, Firefox bookmarks, files, artists and albums in Rhythmbox, Pidgin buddies, etc.).
GNOME Do is plugin based, allowing it to be easily extended to handle new items and actions. This package contains a core set of items and actions.
