 | 
						||
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.")
