generic apt question.

[Adam Shand <larry@alaska.net>]

hey.

at some point in the future i'd like to migrate the web based package
finder i wrote (http://www.spack.org/debian/)to use apt as the back end
(instead of manually ftping the Packages.gz files and hasing them into a
pseudo database.

however one of the features of the package finder is that it allows you to
search unstable, frozen and stable.  i know that in the sources.list file
you can have lines for multiple versions of debian, what i'm not sure of
is if that information is kept seperate for each version or if it is
merged into one "meta" database.

if anyone knows the answer (and can point me at a good resource for this
before i start poking around all the docs) it would be much appreciated.

thanks,
adam.
