-=======================================================
-Capturing configuration information during installation
-=======================================================
-
-.. contents::
-   :local:
-
-The Problem
-===========
-
-Currently the libc++ supports building the library with a number of different
-configuration options.  Unfortunately all of that configuration information is
-lost when libc++ is installed. In order to support "persistent"
-configurations libc++ needs a mechanism to capture the configuration options
-in the INSTALLED headers.
-
-
-Design Goals
-============
-
-* The solution should not INSTALL any additional headers. We don't want an extra
-  #include slowing everybody down.
-
-* The solution should not unduly affect libc++ developers. The problem is limited
-  to installed versions of libc++ and the solution should be as well.
-
-* The solution should not modify any existing headers EXCEPT during installation.
-  It makes developers lives harder if they have to regenerate the libc++ headers
-  every time they are modified.
-
-* The solution should not make any of the libc++ headers dependent on
-  files generated by the build system. The headers should be able to compile
-  out of the box without any modification.
-
-* The solution should not have ANY effect on users who don't need special
-  configuration options. The vast majority of users will never need this so it
-  shouldn't cost them.
-
-
-The Solution
-============
-
-When you first configure libc++ using CMake we check to see if we need to
-capture any options. If we haven't been given any "persistent" options then
-we do NOTHING.
-
-Otherwise we create a custom installation rule that modifies the installed __config
-header. The rule first generates a dummy "__config_site" header containing the required
-#defines. The contents of the dummy header are then prepended to the installed
-__config header. By manually prepending the files we avoid the cost of an
-extra #include and we allow the __config header to be ignorant of the extra
-configuration all together. An example "__config" header generated when
--DLIBCXX_ENABLE_THREADS=OFF is given to CMake would look something like:
-
-.. code-block:: cpp
