I afraid that there are many of them :( 

known bugs:
- when using the "program" tag for the MapLogWriter, it seems (under linux) not to be possible to copy the
  last logfile (with <cp "%n" "%m">). No error shows up in the logfile. It works when using <cp %n %m>. 
  Executing the command from the shell works.
- when executing "echo %mapname" with a ProgramOnEventHandler, no output is shown, neither in the 
  logfile nor in the nohup.out (under linux)
