apt is actually looking for Packages.gz, Sources.gz, and Release.  These
three files contain the information about all sorts of things (depends,
file size, short description, etc).  They also contain the location of
all the files that this apt source contains.  When you type 'apt-cache
show foo', apt retrieves the information about foo, invluding the
absolute URL for foo.deb, from these files (or, I guess more exactly,
from the library it's built out of these files).  I think.

Heisenberg may have been here.
