# Wrapper for the Mersenne Prime Torture test (mprime)
# ====================================================
#
# 'mprime' is a wrapper that automaticly detects the number of CPUs so they can be
# stressed all at the same time. It will run an instance of 'mprime' for each
# CPU in order to heat all CPUs up at the same time. You can do this by running
# the background option (-bn with n= number of processes). However, this option
# does not display any output on the screen. This can be solved by running several
# instances of mprime with the background (&) option of the shell. This method
# displays the output of the multiple instances of mprime.
#
# This wrapper allows the user to choose which version of mprime he wants to use.
#   mprime          ==> will prompt to ask which version should be used
#   mprime 23       ==> will run 'Mersenne Prime 23.5.2'
#   mprime 24       ==> will run 'Mersenne Prime 24.14.2'
#
# This wrapper avoids specifying the working directory part (-W) and the torure
# (-t) option of the command 'mprime -t -W/tmp/torture-test/torture.XXXXXX',
# so the user can run 'mprime' from a terminal without worrying which parameters
# to add to use the torture test of Mersenne Prime Test.
