8656 + reconstruct a .ipk from an installed package, (ie. for beaming

8658 + more fields here, (depends, suggests, etc.), so that that would
8659 + be guaranteed to work even in the absence of more information
8660 + from the available file.
8661 +
8662 + 28-MAR-03: kergoth and I discussed this yesterday. We think
8663 + the essential info needs to be here for all installed packages
8664 + because they may not appear in the Packages files on various
8665 + feeds. Furthermore, one should be able to install from URL or
8666 + local storage without requiring a Packages file from any feed.
