    DESCRIPTION

           Interface module for the Event Trace (ET) application
    
    
    

    EXPORTS

           trace_me(DetailLevel, From, To, Label, Contents) -> hopefully_traced
    
                  Types:
    
                     DetailLevel = integer(X) when X =< 0, X >= 100
                     From = actor()
                     To = actor()
                     Label = atom() | string() | term()
                     Contents = [{Key, Value}] | term()
                     actor() = term()
    
                  A function that is intended to be traced.
    
                  This  function  is intended to be invoked at strategic places in
                  user applications in order to  enable  simplified  tracing.  The
                  functions  are extremely light weight as they do nothing besides
                  returning an atom. The functions are designed for being  traced.
                  The global tracing mechanism in et_collector defaults to set its
                  trace pattern to these functions.
    
                  The label is intended to provide a brief summary of  the  event.
                  It is preferred to use an atom but a string would also do.
    
                  The  contents can be any term but in order to simplify post pro-
                  cessing of the traced events,  a  plain  list  of  {Key,  Value}
                  tuples is preferred.
    
                  Some  events,  such as messages, are directed from some actor to
                  another. Other events (termed actions)  may  be  undirected  and
                  only have one actor.
    
           trace_me(DetailLevel, FromTo, Label, Contents) -> hopefully_traced
    
                  Invokes et:trace_me/5 with both From and To set to FromTo.
    
           phone_home(DetailLevel, FromTo, Label, Contents) -> hopefully_traced
           phone_home(DetailLevel, From, To, Label, Contents) -> hopefully_traced
    
                  These functions sends a signal to the outer space and the caller
                  hopes that someone is listening. In  other  words,  they  invoke
                  et:trace_me/4 and et:trace_me/5 respectively.
    
           report_event(DetailLevel, FromTo, Label, Contents) -> hopefully_traced
           report_event(DetailLevel,   From,   To,   Label,   Contents)  ->  hope-
