+// Background:
+//      This check has been introduced as a workaround for a ROOT feature.
+//      TEnv will not see the last line in a text file, when this last line 
+//      does not end with a \n.
+//
+//      In addition we check for the occurence of \r, since some editors would
+//      place \r instead of \n (unlike windows that uses \n\r), which would
+//      also result in problems.
+//      FIXME: So currently we also complain about "\n\r" and "\r\n" as well as 
+//      "\r  \t   \n" or "\n      \t\t\t\r", which would in fact not be a problem at 
+//      all.
