+ (synopsis "Work with Direct3D shaders on alternate 3D APIs")
+ (description "MojoShader is a library to work with Direct3D shaders on
+alternate 3D APIs and non-Windows platforms. The primary motivation is moving
+shaders to OpenGL languages on the fly. The developer deals with \"profiles\"
+that represent various target languages, such as GLSL or ARB_*_program.
+
+This allows a developer to manage one set of shaders, presumably written in
+Direct3D HLSL, and use them across multiple rendering backends. This also
+means that the developer only has to worry about one (offline) compiler to
+manage program complexity, while MojoShader itself deals with the reduced
+complexity of the bytecode at runtime.
+
+MojoShader provides both a simple API to convert bytecode to various profiles,
+and (optionally) basic glue to rendering APIs to abstract the management of
+the shaders at runtime.")
