How can I test my app against Tracker 3?

Tracker 3 can coexist with Tracker 2 on a system and the two will be completely separate.

Currently our advice is to build tracker-miners.git locally and install into a prefix such as /opt/tracker3.

You will need to start the Tracker daemons manually:

    /opt/tracker3/libexec/tracker-miner-fs-3
    /opt/tracker3/libexec/tracker-extract-3

Your app will then be able to connect to the org.freedesktop.Tracker3* DBus names.
