 rely on Core-C (BSD) which adds an object API on top of the C language.

 ** BUILDING **
-To build mkvalidator you have to build coremake first:
-You can either run ./configure on Linux/OS X or
-- Just compile <root>/corec/tools/coremake/coremake.c with your C compiler.
-- run coremake from the root of the source :
-  * "coremake.exe vs9_win32" to generate the project files for Visual Studio 2008
-  * "coremake gcc_linux" to generate the project files for GNU make building with gcc
-  * "coremake gcc_linux_x64" for GNU make building with gcc on Linux 64 bits
-  * "coremake xcode_uni" to generate the project files for XCode for a universal OS X binary
-  * look in the coremake folder for all the platforms supported
+To build mkvalidator you need CMake and a working C compiler.
 
-  
-The Makefile/mkvalidator.sln will end up in the mkvalidator folder. You just have to
-build from there and it will create mkvalidator(.exe) under <root>/release/
+You just run "cmake ." to generate the makefiles and then "make".
 
-To delete all the project files run "coremake(.exe) clean" from the root of the sources.
+On Windows a Visual Studio project may be created instead.
