+Notes on C++ Modules
+====================
+
+* Clang implements non-intrusive model via module maps, libc++ has one.
+
+* VC implements TS, has some tutorials.
+
+* Seems like multi-file module export may be supported in the future. So the
+  output becomes kind of like a library rather than a precompiled header file.
+
+Questions
+=========
+
+* Is there/will there be support for modules in /showIncludes/-M*? We will
+  need it for all the same reasons as for headers. In a sense, module is an
+  always generated header.
