You can copy-and-paste an existing backend (like akonadi), and then
rename files and classes as needed.

Depending on the kind of PIM storage you need to interface with you need
to implement different interfaces. Most storages support
importing/exporting items in a standard format (like vCard or iCalendar)
and offer some kind of item listing. The TrackingSyncSource is a good
base class for this and comes with full documentation of all virtua
methods that one may have to implement.

I don't know what kind of storage TDE supports. It's likely that you
will have to write a backend for its PIM API.

Backends get detected automatically when placed in src/backends, so just
copy-and-paste, modify, then re-run autogen + configure + make.

kde is the platform support (KWallet). akonadi is the backend for PIM
storage via the Akonadi API. kcalextended is the backend for Nokia's
extended KCal calendar storage (as used in the N9).
