+	# Unfortunatelly we need some fancy post-installation.
+	# Otherwise it wouldn't be possible to load the modules
+	# for H5root and OPAL at the same time. The problem is
+	# the JIT compiler of ROOT and the fact, that we need
+	# a serial HDF5 for H5root but a parallel for OPAL.
+	#
+	# Since ROOT's JIT compiler uses the environment variable
+	# CPLUS_INCLUDE_PATH to search for header files, the 
+	# content of it is cruciale. In other words: it must be 
+	# guaranteed that the header files of the serial compiled
+	# HDF5 are used by ROOT's JIT compiler. Since we have no
+	# influence on the order he modules are loaded, we cannot
+	# guarantee this without checking and - if required - 
+	# changing the search path. 
+	#
+	# The simplest solution for this problem is to install
+	# all required header files of HDF5 and H5hut into the
+	# include directory of the H5root module and to use a
+	# wrapper script to set the right search path.
+	
+	# rename H5root binary, this will be called by a wrapper
+	# script.
