+How come there are different sets of tags in the Packages file and in ``/var/lib/debtags``?
+-------------------------------------------------------------------------------------------
+
+There are a few reasons:
+
+ * Debtags supports merging different tag sources: for example, iterating.org
+   provides a tag source with package rankings and debtags is able to download
+   it and merge it to the other tags.  Tag sources are listed in
+   ``/etc/debtags/sources.list``.  This also allows some of us to use the
+   unreviewed tags on Alioth instead of the ones in the Package database.
+ * For many applications the tags are easier to access when aggregated on a
+   small file rather than by parsing the very large package database
+ * Finally, the debtags database in ``/var/lib/debtags`` is also indexed for
+   fast access.
+
+Have the Packages file as the primary tag storage has never been the main idea,
+although it's turned out to be useful to allow tags to be useable in
+software such as apt-cache, aptitude and grep-dctrl without them having to be
+modified to access an extra database.
