Spice is an open remote computing solution, providing client access to
remote machine display and devices (e.g., keyboard, mouse, audio).
Spice achieves a user experience similar to an interaction with a
local machine, while trying to offload most of the intensive CPU and
GPU tasks to the client. Spice is suitable for both LAN and WAN usage,
without compromising on the user experience.

libcacard is an optional dependency, enabled by passing the switch
CACARD=yes
