+CMake is a build automation system
+  http://en.wikipedia.org/wiki/Cmake
+
+We try to use it as a replacement for the established GNU build system.
+This attempt is currently only experimental. If you wonder why anyone
+should do this, read
+
+  Why the KDE project switched to CMake -- and how 
+  http://lwn.net/Articles/188693/
+  Escape from GNU Autohell!
+  http://www.shlomifish.org/open-source/anti/autohell
+
+- How can I get GNU Awk compiled with CMake as fast as possible ?
+  git clone git://git.savannah.gnu.org/gawk.git
+  cd gawk
+  git checkout cmake
+  mkdir build
+  cd build
+  cmake ..
+  make
+  ./gawk --version
+  make test
+Notice that this git-checkout allows you to read the source code,
+track the cmake branch and get updates. You will not be able to
+commit anything.
+
+- How can I use git to contribute source code ?
+You need an account at Savannah. Read this to understand the first steps:
+  http://savannah.gnu.org/maintenance/UsingGit
+  README.git
+Use your account there to register your public ssh key at Savannah.
+Then you are ready to checkout. Remember that (when cloning) you are
+setting up your own local repository and make sure you configure it
+properly.
+  git clone ssh://my_account_name@git.sv.gnu.org/srv/git/gawk.git
+  git config --global user.name "first-name last-name"
+  git config --global user.email First.Last@email.com
+  git config --global color.ui auto
+
+- What is the current status of the cmake branch ?
+It has just begun, pre-alpha, unclear if it will ever be taken up
+by the maintainer. We want to study if using CMake with such a
+basic tool like gawk is feasible and if it easier to use than
+the GNU build system.
+
+- Where can I find a tutorial on CMake basics ?
+Use the "official tutorial":
+  http://www.cmake.org/cmake/help/cmake_tutorial.html
+
+- Where is the reference of all commands and variables ?
+Depending on the CMake version you use, select one of these:
+  http://www.cmake.org/cmake/help/v2.8.10/cmake.html
+
+- How can I cross-compile ?
+Proceed in the same way as explained above for native compilation,
+but use a different build directory. When using CMake, do this:
+  cmake -DCMAKE_TOOLCHAIN_FILE=../cmake/Toolchain_mingw32.cmake ..
+Write a new Toolchain file for your cross-compiler and use it.
+
+- How can I build an installable file ?
+Use "make package". The exact kind of installable file depends on your
+operating system and defaults to TGZ.
+
+- Can I build an executable that runs on any Win32 platform ?
+It is possible to build for the target Win32, but only with cross-compilers
+on certain platforms. You need a MinGW cross-compiler and the NSIS package
+builder.
