+/** @file INSTALL
+@brief Installation Instructions
+*******************************
+
+For Debian based GNU / Linux
+============================
+Tested development platform: Ubuntu 14.4 amd64.
+
+Build dependencies are:
+    build-essential cmake libqt5core5a qttools5-dev-tools qt5-default \
+    qtbase-dev qtbase5-dev-tools qttools5-dev inkscape
+
+
+This document expects the following setup for build and installation.
+It is recommended to set a custom installation prefix to avoid root
+privileges.
+
+    export CUSTOM_PREFIX=<Prefix of your choice (default /usr)>
+    mkdir -p $CUSTOM_PREFIX/bin
+    export PATH=$CUSTOM_PREFIX/bin:$PATH
+
+Building the Software:
+    cd <PATH_TO_REPO>
+    mkdir build-native
+    cd build-native
+    cmake .. -DCMAKE_PREFIX_PATH=$CUSTOM_PREFIX
+
+For Microsoft Windows
+=====================
+The Windows variant should be cross compiled from a Debian based GNU/Linux
+system. The minimum requirement is Debian stable.
+
+Tested development platform is Ubuntu 14.4
+
+Dependencies on the Host system:
+
+    apt-get install git autoconf automake bash bison bzip2 \
+    cmake flex gettext git g++ intltool \
+    libffi-dev libtool libltdl-dev libssl-dev \
+    libxml-parser-perl make openssl patch perl \
+    pkg-config scons sed unzip curl xz-utils autopoint \
+    gperf
+
+Build the windows binaries:
+
+    MXEPATH=$CUSTOM_PREFIX/win
+    git clone https://github.com/Intevation/mxe.git $MXEPATH
+    cd $MXEPATH
+    git checkout replay-it
+    echo "MXE_TARGETS := i686-w64-mingw32.static" > settings.mk
+    make qtbase
+
+Add CMAKE_STRIP to the toolchain file:
+
+    echo "set(CMAKE_STRIP $MXEPATH/usr/bin/i686-w64-mingw32.static-strip)" >> \
+        "$MXEPATH/usr/i686-w64-mingw32.static/share/cmake/mxe-conf.cmake"
+
+Compile the software:
+
+    cd repo
+    mkdir build-windows
+    cd build-windows
+    MXETARGET=$MXEPATH/usr/i686-w64-mingw32.static/
+    cmake .. \
+        -DCMAKE_PREFIX_PATH="$MXETARGET/qt5;$MXETARGET;" \
+        -DCMAKE_TOOLCHAIN_FILE="$MXETARGET/share/cmake/mxe-conf.cmake" \
+        -DCMAKE_VERBOSE_MAKEFILE=True
