+Installation instructions for the Evidence Data Display Edd
+
+A) The packages Qt, Qwt and DIM are needed
+
+1. Qt can be downloaded from http://qt.nokia.com/. 
+
+   Test have been made with version 4.6.2 which can be downloaded aat
+   ftp://ftp.qt.nokia.com/qt/source/qt-everywhere-opensource-src-4.6.2.tar.gz.
+   It should well work with later version as well. 
+   
+   Installation instruction are given in the package. Usually, they amount on
+   Linux to executing './configure', then 'gmake all' followed by 
+   'gmake install', all done within the unpacked directory.
+ 
+   Before the following steps, it should be assured that the right version
+   of qmake is used, as many Linux installations include an older version
+   of Qt. Use 'qmake -version' to check and adjust your PATH variable if
+   necessary.
+    
+2. Qwt can be downloaded from http://sourceforge.net/projects/qwt/.
+   
+   Tests were made with version 5.2.1. Installation should simply be done
+   by executing 'qmake', then 'make', and finally 'make install'.
+
+3. DIM can be downloaded from http://dim.web.cern.ch/dim/.
+
+   The latest available version should be fine. Follow the installation
+   instruction on the web site given at the download link. Note that the
+   command line option in 'unzip -a' is mandatory. Compiling is done
+   with 'gmake all'.
+
+
+B) Compiling Edd
+
+An environment variable QWTDIR should point to the Qwt installation,
+and DIMDIR to the DIM installation.
+
+The subversion repository should preferably be checked out fully, as
+the class describing the M0 raw data format is currently needed.
+
+Issue 'qmake', then 'make' will build the executable Edd.
+
+To start, the environment variable LD_LIBRARY_PATH needs to include the
+location of the Qwt shared library.
