# Checks on the half-hour if I have any new "Gmails".
# I don't know how to make this access the Gnome keyring so for now the script
# resides in an "ecryptfs" encrypted "Private" directory ie. username and pass
# in plain sight whilst logged in - good enough? - maybe not for the paranoid!
# You'll need to supply a bing bong sound and an icon.
# Add this to your user crontab - all on one line without the hash character.
