+=====
+
+1. Problems with macro-execution
+--------------------------------
+
+A failed macro-execution can leave CINT in a poorly defined state that
+prevents further execution of macros. For example:
+
+  Exception Reve::Exc_t: Event::Open failed opening ALICE ESDfriend from
+  '/alice-data/coctail_10k/AliESDfriends.root'.
+
+  root [1] Error: Function MUON_geom() is not defined in current scope  :0:
+  *** Interpreter error recovered ***
+  Error: G__unloadfile() File "/tmp/MUON_geom.C" not loaded  :0:
+
+'gROOT->Reset()' helps in most of the cases.
