+Additional CMake Modules
+========================
+
+Introduction
+------------
+
+This is a collection of additional CMake modules.
+Most of them are from Ryan Pavlik (<http://academic.cleardefinition.com>).
+
+How to Integrate
+----------------
+
+These modules are probably best placed wholesale into a "cmake" subdirectory
+of your project source.
+
+If you use Git, try installing [git-subtree][1],
+so you can easily use this repository for subtree merges, updating simply.
+
+For the initial checkout:
+
+	cd projectdir
+
+	git subtree add --squash --prefix=cmake git://github.com/bilke/cmake-modules.git master
+
+For updates:
+
+	cd projectdir
+
+	git subtree pull --squash --prefix=cmake git://github.com/bilke/cmake-modules.git master
+
+
+How to Use
+----------
+
+At the minimum, all you have to do is add a line like this near the top
+of your root CMakeLists.txt file (but not before your project() call):
+
+	list(APPEND CMAKE_MODULE_PATH "${CMAKE_SOURCE_DIR}/cmake")
+
+You might also want the extra automatic features/fixes included with the
+modules, for that, just add another line following the first one:
+
+	include(UseBackportedModules)
+
+
+Licenses
+--------
+
+The modules that are written by Ryan Pavlik are all subject to this license:
+
+> Copyright Iowa State University 2009-2011
+>
+> Distributed under the Boost Software License, Version 1.0.
+>
+> (See accompanying file `LICENSE_1_0.txt` or copy at
+> <http://www.boost.org/LICENSE_1_0.txt>)
+
+Modules based on those included with CMake are under the OSI-approved
+BSD license, which is included in each of those modules.  A few other modules
+are modified from other sources - when in doubt, look at the .cmake.
+
+Important License Note!
+-----------------------
+
+If you find this file inside of another project, rather at the top-level
+directory, you're in a separate project that is making use of these modules.
+That separate project can (and probably does) have its own license specifics.
