dapper is a simple lightweight desktop application auto-starter. It will read
.desktop files in the autostart directories, all according to the FreeDesktop
autostart specifications.
You can define which desktop to start applications for (e.g. GNOME, XFCE, etc)
in configuration file (~/.config/dapper.conf) or from command line.
Note that autostarting desktop application is probably already taken care of if you do use a desktop environment/session manager.
