## Use in conjunctin with the Bash functions start-leap() and stop-leap()
## to replace automatic startup with manual startup/shutdown :
##
## Add these two functions to your .bashrc and you will then be able to start
## and stop the Leap Motion daemon and agent simply by typing "start-leap" and
## "stop-leap" at the Bash shell prompt.
