I've just committed this documentation patch, which describes the new
C++0x branch (cxx0x-branch) and its contents.

  <h1>C++0x Language Support in GCC</h1>

  <p>C++0x is the working name of the next ISO C++ standard, due by
  the end of this decade, which introduces a host of new features into
  the standard C++ language and library. This project seeks to
  implement new C++0x features in GCC and to make it one of the first
  compilers to bring C++0x to C++ programmers.</p>

  <p>C++0x features are available both as part of the "mainline" GCC
  compiler and on the C++0x branch in the Subversion repository. For
  the mainline compiler, one should use the
  flags <code>-std=gnu++0x</code> or <code>-std=c++0x</code> to
  request C++0x features. In the branch C++0x
  compiler, <code>-std=gnu++0x</code> is the default. Moreover, the
  branch C++0x compiler will often have additional C++0x features that
  have not yet migrated to mainline GCC.</p>

  <p>The C++0x development branch is maintained by Douglas Gregor
    <<a
    href="mailto:doug.gregor@gmail.com">doug.gregor@gmail.com</a>>
    and Jason Merrill <<a
href="jason@redhat.com">jason@redhat.com</a>>.</p>

<h2>Features</h2>

  <p>The following C++0x features are currently available on the C++0x
  branch. Features that contain a [patch] link are not yet available
  in the mainline compiler. </p>

<h2>Getting the C++0x compiler</h2>

  <p>The C++0x compiler is available under
    the <code>cxx0x-branch</code> branch in the GCC Subversion
    repository. To retrieve the C++0x branch via Subversion, use:</p>

  <pre>
svn -q checkout svn://gcc.gnu.org/svn/gcc/branches/cxx0x-branch gcc0x
  </pre>

<h2>Development Process</h2>
<p>Development of C++0x features occurs both on a dedicated C++0x
  branch and in the mainline compiler. Contributors are encouraged to
  submit their patches for the mainline compiler; we will also pick up
  the patches for the C++0x branch. Please put <code>[C++0x]</code> in
  the subject of your message to identify C++0x features.</p>

<p>When committing to the C++0x branch, please append ChangeLog
  entries to ChangeLog.cxx0x in the root of the branch.</p>
