+SUMMARY="OpenGL and OpenGL ES shader front end and validator"
+DESCRIPTION="Khronos reference front-end for GLSL and ESSL, and sample SPIR-V generator
+
+There are several components:
+
+* Reference Validator and GLSL/ESSL -> AST Front End
+An OpenGL GLSL and OpenGL|ES GLSL (ESSL) front-end for reference validation and translation of \
+GLSL/ESSL into an internal abstract syntax tree (AST).
+Status: Virtually complete, with results carrying similar weight as the specifications.
+
+* HLSL -> AST Front End
+An HLSL front-end for translation of an approximation of HLSL to glslang's AST form.
+Status: Partially complete. Semantics are not reference quality and input is not validated.
+This is in contrast to the DXC project, which receives a much larger investment and attempts to \
+have definitive/reference-level semantics.
+See issue 362 and issue 701 for current status.
+
+* AST -> SPIR-V Back End
+Translates glslang's AST to the Khronos-specified SPIR-V intermediate language.
+Status: Virtually complete.
+
+* Reflector
+An API for getting reflection information from the AST, reflection types/variables/etc. from the \
+HLL source (not the SPIR-V).
+Status: There is a large amount of functionality present, but no specification/goal to measure \
+completeness against.  It is accurate for the input HLL and AST, but only approximate for what would later be emitted for SPIR-V.
+
+* Standalone Wrapper
+glslangValidator is command-line tool for accessing the functionality above.
+Status: Complete.
+Tasks waiting to be done are documented as GitHub issues."
