8549 +       needed for actual computation, (package, version, status,
8550 +       essential, conffiles). The assumption is that all other fields
8551 +       can be found in th available file.
8552 +
8553 +       But, someone proposed the idea to make it possible to
8554 +       reconstruct a .ipk from an installed package, (ie. for beaming
8555 +       from one handheld to another). So, maybe we actually want a few

8557 +       be guaranteed to work even in the absence of more information
8558 +       from the available file.
8559 +
8560 +       28-MAR-03: kergoth and I discussed this yesterday.  We think
8561 +       the essential info needs to be here for all installed packages
8562 +       because they may not appear in the Packages files on various
8563 +       feeds.  Furthermore, one should be able to install from URL or
8564 +       local storage without requiring a Packages file from any feed.
