Basic DerelictOrg and Deimos question

[WhatMeWorry via Digitalmars-d-learn]

within DerelictOrg, I've used DerelictGL3 and DerelictGLFW3 
packages successfully. But just today I stumbled across 
D-Programming-Deimos and noticed that it has a glfw and an OpenGL 
as well.

I've read some of the descriptions and Derelict talks about 
"dynamic bindings" where Deimos mentions "D interfaces".

Just for clarity's sake, should I consider the DerelictOrg and 
Deimos (packages, projects, or libraries) as separate from one 
another?  Or does DerelictOrg use Deimos behind the scenes?
