 changes since 0.16.0
 ===================================
 NEW 2016-01-22 update of the docu which now describes the RRF option.
+CHANGED 2016-02-17 start to move the startup XML-files to $HOME/.musrfit
+               rather than having it within $prefix/bin.
 CHANGED 2016-02-16 if the LEM file is created 2012 or later and the
                data-file-format tag is still ROOT-NPP or ROOT-PPC, it
                will automatically switched to MUSR-ROOT. This way red/green
