The following only applies to the cvs version.
I have done some performance optimisations in the database handling (the get_all() and sets() operations should now be about 1000 times faster than before). This has the unfortunate effect that you have to rebuild the database from scratch as I needed to add things to the database. If you have saved all the xml:s, this shouldn't be a problem though, just do the following (or similar depending on your OS):
$ mattricks.py import /path/to/your/hrfs/and/xmls/*.xml
