To install the extractor you need to run:

	(cd src/tracker-extract; sudo make install)
      

You can then test the extract in a standalone fashion using:

	echo -e "filename\nmimetype" | tracker-extract 
      

	echo -e "/tmp/a.m3u\naudio/x-mpegurl" | tracker-extract
      

Once the extractor is working, install tracker (to put the category and property descriptions in the right place).

Remove ~/.local/share/tracker/data/common.db. This database in the user home directory is the cache of categories and properties. Right now we don't support automatic upgrade, so you need to remove it by hand. This will be fixed in future releases.
