Synchronise calendars and contacts

In this digital age, we all have digital address books with the phones and addresses of our loved ones, friends, and those with whom we work. We keep calendars with meetings we need to attend and places we are expected to be. And we need to keep this information synchronised across devices, shared with others, but only with those whom we choose to collaborate. Vdirsyncer synchronises address books and calendars between webcal, caldav, and local vdir collections. This empowers users to manage their own data, synchronise with servers of their choice, as well as interact with their data offline in their own devices. Vdirsyncer has proven itself a useful tool, but suffers from some early design issues which are impossible to fix without rewriting it. Within this project, the rewrite will become a reality. Additionally, the codebase will be structured to be easily usable by other projects and developers.
