#initial attempt at an automation script: ltprun
#       3/12/02 William Jay Huie (creation)
#       3/28/02 William Jay Huie minor updates
#this will be kicked off by ltp_master from the master control machine which
#uploads this script and then telnets into each machine and kick this script off
#perhaps by passing a uniq ID to name the LTP_OUTPUT_TAR file by, or 
#allowing the script to create a unique name itself (reccommended for now)
#Check ltp_master for details
#FIXME: One problem is that the tests need to be run as root and this script
#       doesn't as of yet su
#
#CHANGEME:

#This is the user to get the ltp.tgz file from, not who we're running as,
#     that's ocntrolled by ltp_master
