# Oftentimes this script runs so long you'll go to sleep.
# But you don't want the script to die when your computer goes to sleep.
# So consider invoking this with nohup (i.e. "nohup ./logAllBuildroot.sh")
# You can run "tail -f nohup.out" to see what would've
# outputted to the terminal if you didn't use nohup
