+ 1. Basic syntax
+ 2. How do I...
+ 3. Crosscompiling using CMake
+ 4. Creating an installer binary for Windows
+
+This readme explains the most common parameters to CMake needed for
+building mana, as well as setting up a cross build environement to
+create Windows builds.
+
+
+1. Basic syntax
+---------------
+
+cmake [options] <source directory>
+
+If you don't need any special options just change to the directory where
+you extracted the sources and do `cmake . && make'
+
+The syntax for setting variables to control CMakes behaviour is
+-D <variable>=<value>
+
+
+2. How do I...
+--------------
+
+- Use a custom install prefix (like --prefix on autoconf)?
+  CMAKE_INSTALL_PREFIX=/path/to/prefix
+- Create a debug build?
+  CMAKE_BUILD_TYPE=Debug .
+- Add additional package search directories?
+  CMAKE_PREFIX_PATH=/prefix/path
+- Add additional include search directories?
+  CMAKE_INCLUDE_PATH=/include/path
+
+For example, to build mana to install in /opt/mana, with libraries in
+/build/mana/lib, and SDL-headers in /build/mana/include/SDL you'd use
+the following command:
+
+cmake -D CMAKE_PREFIX_PATH=/build/mana \
+  -D CMAKE_INCLUDE_PATH=/build/mana/include/SDL \
+  -D CMAKE_INSTALL_PREFIX=/opt/mana .
+
+
+3. Crosscompiling using CMake
+-----------------------------
+
+The following example assumes you're doing a Windows-build from within a
+UNIX environement, using mingw32 installed in /build/mingw32.
+
+- create a toolchain-file describing your environement:
+$ cat /build/toolchain.cmake
+# the name of the target operating system
+SET(CMAKE_SYSTEM_NAME Windows)
+
+# toolchain prefix, can be overridden by -DTOOLCHAIN=...
+IF (NOT TOOLCHAIN)
+    SET(TOOLCHAIN "i386-mingw32-")
+ENDIF()
+
+# which compilers to use for C and C++
+SET(CMAKE_C_COMPILER ${TOOLCHAIN}gcc)
+SET(CMAKE_CXX_COMPILER ${TOOLCHAIN}g++)
+
+# here is the target environment located
+SET(CMAKE_FIND_ROOT_PATH  /build/mingw32 /build/mana-libs )
+
+# adjust the default behaviour of the FIND_XXX() commands:
+# search headers and libraries in the target environment, search
+# programs in the host environment
+set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
+set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
+set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
+
+
+- set your PATH to include the bin-directory of your mingw32-installation:
+$ export PATH=/build/mingw32/bin:$PATH
+
+- configure the source tree for the build, using the toolchain file:
+$ cmake -DCMAKE_TOOLCHAIN_FILE=/build/toolchain.cmake .
+
+- use make for building the application
+
+
+4. Creating an installer binary for Windows
+-------------------------------------------
+
+Call cmake with the following flags:
+
+ - CMAKE_TOOLCHAIN_FILE=/build/toolchain.cmake
+   The path to your toolchain file from chapter 3
+ - VERSION=$VERSION
+   The version number for the build, used to set client identification and
+   EXE meta information. Needs to be in the form Major.Minor.Release.Build
+ - CMAKE_BUILD_TYPE=RelWithDebInfo|Release
+   RelWithDebInfo is the prefered build type, as it provides some backtrace
+   information without blowing the binary up too much. Don't use Debug.
+
+Install nsis (on Debian, apt-get install nsis), and get the UnTGZ plugin:
+    http://nsis.sourceforge.net/UnTGZ_plug-in
+Place untgz.dll in nsis plugins directory (on Debian, /usr/share/nsis/Plugins/)
+
+Now chdir to packaging/windows. Make sure you have the msgfmt program (from
+gettext), and execute make-translations.sh to generate translations from the
+po-files in ../../translations/
+
+Check that you've got the translations, and call `makensis setup.nsi' with the
+following parameters:
+
+ -DDLLDIR=/build/mana-libs/lib/
+  The directory you've put the libraries. It's the one from the toolchain file
+  with /lib/ added at the end. If you'd like to include the Dr. MingW crash
+  handler place exchndl.dll in this directory.
+ -DPRODUCT_VERSION=$VERSION
+  Same as above
+ -DUPX=true
+  Set to upx if you'd like to compress the binaries using upx (and install upx,
+  of course). Will remove debug symbols.
+ -DEXESUFFIX=/src
+  Suffix to the source directory, pointing to the directory where the binaries
+  are. For cmake-builds that's /src.
+
+To build the installer for the 0.1.0.0 release you'd do the following:
+$ cmake -DVERSION=0.1.0.0 -DCMAKE_BUILD_TYPE=RelWithDebInfo \
+      -DCMAKE_TOOLCHAIN_FILE=/build/toolchain.cmake .
+[...]
+$ make
+[...]
+$ cd packaging/windows
+$ ./make-translations.sh
+[...]
+$ makensis -DDLLDIR=/build/mana-libs/lib/ -DPRODUCT_VERSION=0.1.0.0 \
+           -DUPX=true -DEXESUFFIX=/src setup.nsi
+
+and end up with the installer in mana-0.1.0.0-win32.exe
