We have an page dedicated to compliation databases including
various ways to generate them, but we don't mention that clang
has a built in method to do this.  This addresses that.

 =================
 
+Clang has the ablity to generate compilation database fragments via
+the :option:`-MJ argument <clang -MJ\<arg>>`. You can contantinate those
+fragments together between ``[`` and ``]`` to create a compilation database.
+
 Currently `CMake <https://cmake.org>`_ (since 2.8.5) supports generation
 of compilation databases for Unix Makefile builds (Ninja builds in the
 works) with the option ``CMAKE_EXPORT_COMPILE_COMMANDS``.
