%description
The Extensible Virtual Display Interface (EVDI) is a Linux kernel module
that enables management of multiple screens, allowing user-space programs
to take control over what happens with the image. It is essentially
a virtual display you can add, remove and receive screen updates for, in
an application that uses the libevdi library.
