Barbarella is a user-configurable buttonbar intended to provide single-click access to applications and commands for simple Linux GUIs such as fluxbox. The content of each bar (icons, tooltips, and programs to be launched) is entirely determined by a configuration file with a simple syntax. Each line in the file defines one button. The default configuration file is $HOME/.barbarella.conf, but other files can be used, allowing users to have different buttonbars for different purposes.
