+"""cmake output module
+
+This module is under development and should be considered experimental.
+
+This module produces cmake (2.8.8+) input as its output. One CMakeLists.txt is
+created for each configuration.
+
+This module's original purpose was to support editing in IDEs like KDevelop
+which use CMake for project management. It is also possible to use CMake to
+generate projects for other IDEs such as eclipse cdt and code::blocks. QtCreator
+will convert the CMakeLists.txt to a code::blocks cbp for the editor to read,
+but build using CMake. As a result QtCreator editor is unaware of compiler
+defines. The generated CMakeLists.txt can also be used to build on Linux. There
+is currently no support for building on platforms other than Linux.
+
+The generated CMakeLists.txt should properly compile all projects. However,
+there is a mismatch between gyp and cmake with regard to linking. All attempts
+are made to work around this, but CMake sometimes sees -Wl,--start-group as a
+library and incorrectly repeats it. As a result the output of this generator
+should not be relied on for building.
+
+When using with kdevelop, use version 4.4+. Previous versions of kdevelop will
+not be able to find the header file directories described in the generated
+CMakeLists.txt file.
