I abandoned the project I built this for, and am no longer actively working on it.
High level bindings to evdi, a program for managing virtual displays on linux.
Warning: This is alpha-quality software. If it breaks something maybe try rebooting your computer.
Evdi doesn't full document the invarients necessary for memory safety, so I'm not confident this library is sound yet.
See also the low-level unsafe bindings evdi-sys, and the docs for libevdi.
