Updating from Chronometer2

To update PADD from chronometer2:

• Get the latest version of PADD:

cd ~
wget -N https://raw.githubusercontent.com/jpmck/PADD/master/padd.sh
chmod +x padd.sh

• Edit the end of ~/.bashrc:

# Run PADD
# If we're on the PiTFT screen (ssh is xterm)
if [ "$TERM" == "linux" ] ; then
    while :
    do
      ./padd.sh
      sleep 1
    done
fi

• Remove the old chronometer2 script:

rm -f chronometer2.sh
