+Here, glslang proper means core GLSL parsing, HLSL parsing, and SPIR-V code
+generation. Glslang proper requires use of two licenses, one that covers
+non-preprocessing and an additional one that covers preprocessing.
+
+Bison was removed long ago. You can build glslang from the source grammar,
+using tools of your choice, without using bison or any bison files.
+
+Other parts, outside of glslang proper, include:
+
+- gl_types.h, only needed for OpenGL-like reflection, and can be left out of
+  a parse and codegen project.  See it for its license.
+
+- update_glslang_sources.py, which is not part of the project proper and does
+  not need to be used.
+
+- the SPIR-V "remapper", which is optional, but has the same license as
+  glslang proper
+
+- Google tests and SPIR-V tools, and anything in the external subdirectory
+  are external and optional; see them for their respective licenses.
