 GNOME PPP is an easy to use graphical dialup connection configuring
 and dialing tool with system tray icon support.
 .
 It uses GNOME/GTK+ for its graphical interface and integrates well
 in GNOME desktop environment, but it can be used in other environments.

 It also uses WvDial dialer as its backend, providing simple configuration
 via config files. You can also use plain wvdial if you don't have X running.
