Installation

You can install BeThere via the included install.sh script and the default values will serve you well. If you don't feel like doing that, here is how to install by hand.

Edit BeThere_settings to reflect where public, and private entries should be stored, and where alarms should be stored. You can also edit the TIME_FORMAT field if you please.
Copy BeThere_settings to /boot/home/config/settings
Run mimeset -f /boot/apps/Monkeyworks/BeThere/BeThere to register the mime types

That's all that's required! I suggest that you also edit /boot/home/config/boot/UserBootscript to automatically run alarm_daemon
