# This script is for use on the machine where the nightly Expeditee binaries are to be 
# uploaded. Put this script in the same folder as the uploads are meant to go.
# When any binary's log *.out file is being uploaded via secure shell (which is fast), 
# this script's called. The invocation of this script should go into .ssh/authorizedkeys.
# Then this script will delete all other log and binary files in this folder for the same
# os-release that are not of the current date (in case it's the uploaded file itself). 
# The code didn't work if the binary was processed independent of the log file, since the 
# bin's filename (and hence target os) could not be determined as it was still being 
# uploaded.
