-ns: Output namespace (e.g. -ns:OpenTK.Graphics).
Default: OpenTK.Graphics.OpenGL

-class: Output class (e.g. -class:GL3).
Default: GL/Wgl/Glu/Glx (depends on -mode)
-o/-option: Set advanced option. Available options:
-o:tao Tao compatibility mode.
-o:enums Follow OpenGL instead .Net naming conventions.
-o:safe Do not generate public unsafe functions.
-o:enums_in_class
Place enums in a nested class (i.e. GL.Enums)
instead of a namespace (i.e. OpenTK.Graphics.OpenGL.Enums)
