+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/
+
+- How can I get gawk 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.
