# August 2005, M. Spiekermann. Major changes. A function for calling the tests
# was added. And each test command is run with a timeOut. The log files of all
# failed test are stored in a tar file.
#
# Januar 2006, M. Spiekermann. Usage of the ~nice~ command added. 
#
# Sept 2006, M. Spiekermann. New parameter added

# include function definitions
