Osmo is a handy personal organizer which includes calendar, tasks
manager and address book modules. It was designed to be a small,
easy to use and good looking PIM tool to help to manage personal
information.

libnotify, libical, libsyncml (available at SBo), and libgringotts
(not available at SBo) are optional build time dependencies.
