+ "SPIRV-Cross tries hard to emit readable and clean output from the
+SPIR-V. The goal is to emit GLSL or MSL that looks like it was written by
+a human and not awkward IR/assembly-like code.
+
+NOTE: Individual features are expected to be mostly complete, but it is
+possible that certain obscure GLSL features are not yet supported. However,
+most missing features are expected to be ``trivial'' improvements at this
+stage.")
