ChangeLog.md

 
 ## OpenRaider (0.1.3) xythobuz <xythobuz@xythobuz.de>
 
+    [ 20141010 ]
+    * Added CPack packaging to the CMake script
+    * Added suitable install target for the Mac App Bundle
+    * Now also trying to load config from ${DESTDIR}/etc/OpenRaider.ini if all else fails
+    * Added suitable install target for Linux that does not need a setup script
+
     [ 20141008 ]
     * Added freeGLUT windowing system to use if SDL2 is not available. Not yet working 100%.
     * Moved unnecessarily duplicated code to Window base class

-On Mac OS X, running `make install` will produce a (more or less) distributable OpenRaider.app bundle.
+On Mac OS X, running `make install` will produce a (more or less) distributable OpenRaider.app bundle, which will be put into /Applications.
+
+On Linux, running `make install` will install OpenRaider to /usr/local/... (the executable in bin, the config in etc, the data files in share). You can change this path with `make install DESTDIR=”/some/where”`
 
 Run `make check` to build and run the unit tests.
 
 ### Configuration file
 
 OpenRaider will try to load `~/.OpenRaider/OpenRaider.ini` or, if it doesn't exist, `OpenRaider.ini` from the current directory.
+
 Running `make setup` will create a minimal configuration in your home directory.
 
 The configuration file format is very simple:

cmake/setup.sh

 #!/bin/sh
 
 echo "Setting up OpenRaider for user $USER..."
+
 mkdir -p ~/.OpenRaider
-cp data/OpenRaider.ini ~/.OpenRaider/
 mkdir -p ~/.OpenRaider/paks
 mkdir -p ~/.OpenRaider/music
 mkdir -p ~/.OpenRaider/data
 mkdir -p ~/.OpenRaider/sshots

 cp data/*.tga ~/.OpenRaider/data
 cp data/*.ttf ~/.OpenRaider/data
 cp data/*.pc ~/.OpenRaider/data
+
 echo "DONE"

     echo "Setting up OpenRaider for user $USER..."
