Remmina is a remote desktop client written in GTK+, aiming to be 
useful for system administrators and travellers, who need to work 
with lots of remote computers in front of either large monitors or 
tiny netbooks. Remmina supports multiple network protocols in an 
integrated and consistant user interface. Currently RDP, VNC, NX, 
XDMCP and SSH are supported.

Optional support for extra features can be enabled with some switches:
AVAHI=ON     (Avahi/Zeroconf, requires avahi, default OFF)
TELEPATHY=ON (Telepathy, default OFF)
