 <code>make all</code> should work to compile the library and the example in ''anal02.C''.  For implementing your own analysis, please check the ''anal02.C'' and ''Zprime_Py8::analyze(Event& rEvt)'' (your playground) in ''Zprime_Py8.C'' as examples. The program supports a few command line arguments
 <code>
-anal02.exe --help --mu=<mu> --nevts=<number of (signal) events
+anal02.exe --help --mu=<mu> --nevts=<number of (signal) events>
            --sigflist=<text file with list of signal files>
            --puflist=<text file with list of pile-up files>
 </code>
+Some hints:
+  * ''--help'' prints a brief usage instruction (which I think is not up-to-date, so please ignore!)
+  * ''--mu=<mu>'' expects the number of interactions per event. if ''<mu> < 0'', exactly ''|<mu>|'' interactions are collected into one event. ''<mu> > 0'' means a Poisson-distributed number of pile-up interactions will be collected from the pile-up (minimum bias) event samples.
+    * if you specify both signal and pile-up input, ''<mu>'' should be the number of pile-up events to be added to one signal event
