network management framework (GNOME frontend)

NetworkManager attempts to keep an active network connection available at
all times. It is intended only for the desktop use-case, and is not
intended for usage on servers. The point of NetworkManager is to make
networking configuration and setup as painless and automatic as possible.
If using DHCP, NetworkManager is _intended_ to replace default routes,
obtain IP addresses from a DHCP server, and change nameservers whenever it
sees fit.

This package contains a systray applet for GNOME's notification area but
it also works for other desktop environments which provide a systray like
KDE or XFCE. It displays the available networks and allows to easily
switch between them. For encrypted networks it will prompt the user for
the key/passphrase and it can optionally store them in the gnome-keyring.
