Ah, but then ClangPlugins.html seems the wrong place. Also, since clang is
pretty nicely modularized here, the process seems to be: look into the
Makefiles or CMakeLists.txt for the libraries you use, build the transitive
closure, and link that in? Not sure there's a better way to document this,
as those dependencies change...
