2014-02-25	record package metadata that describes co-installability	Helmut Grohne
	Specifically all entries in the Conflicts header are saved in the conflict table, all entries in the Provides header are saved in the provide table (to cover conflicts with virtual packages) and packages using dpkg-divert in preinst get a magic "_dpkg-divert" entry in their conflict table. With this metadata it should be possible to compute undeclared file conflicts.
2013-09-02	add option -d --database for db path to all scripts	Helmut Grohne

2013-07-24	readyaml: cache the whole function table	Helmut Grohne
	This should reduce the query bandwidth to the rdbms.
2013-07-23	schema: reference hash functions by integer key	Helmut Grohne
	This already worked quite well for package.id. On a test data set of 5% size this transformation reduces the database size by about 4%.
2013-07-10	schema: reference package table by integer key	Helmut Grohne
	One approach to improve performance is to reduce the database size. A package name takes up 15 bytes in average. A number of a package takes up two bytes. Multiply that difference with the number of references and it should be noticeably. A small test set show a reduction by 10%.
2013-06-11	autoimport: don't fork for readyaml	Helmut Grohne
	This appears to be a huge performance boost.
2013-06-10	split the import phase to a yaml stream	Helmut Grohne
	importpkg.py now emits a yaml stream instead of updating the database. The acutual updating now happens in readyaml.py. In this process autoimport.py was significantly reworked to import packages in parallel.
