# Java* Fuzzer test generator
#
# Modifications 2017-2018: Nina Rinskaya (Azul Systems), Ivan Popov (Azul Systems)
#----------------------------------------------------------

#--------------------------------------------------------------------------------
# Run the Fuzzer tool through rt.sh script in multiple processes.
# Parameters:
#    -NP <int>  - number of processes to launch (default: 5)
#    -NT <int>  - number of tests to generate and run
#    -R <path>  - path to a dir for storing results
#    -P <str>   - string for forming test name prefix like this: <str>$<number of process>-.
#                 For example, "-P a" leads to prefixes a1-, a2-, ... (default: n|o|"")
#    -A <rest>  - the rest of arguments are passed to rt.sh
