# Note: unlike the other try.sh/try.alt.sh scripts we don't use options that
# don't reset the terminal and that quit less(1) when it reaches EOF. This is
# because if we do the effect will vanish the moment they reach the EOF. Also if
# we don't have less(1) reset things the colour of the rest of the script will
# be wrong. Thus in this script the user must hit 'q' to finish this command.
