EGL is a cross-platform between OpenGL / OpenGL ES and native platform windowing systems. On Linux it allows using OpenGL without depending on X. cl-egl is a Common Lisp wrapper for libEGL.

cl-egl is being developed primarily in support of ulubis and is therefor feature incomplete. Pull requests adding more of the API are more than welcome.

cl-egl (obiously) requires libEGL. It is likely that libEGL already exists on your Linux installation if it is recent.
