8472 + more fields here, (depends, suggests, etc.), so that that would
8473 + be guaranteed to work even in the absence of more information
8474 + from the available file.
8475 +
8476 + 28-MAR-03: kergoth and I discussed this yesterday. We think
8477 + the essential info needs to be here for all installed packages
8478 + because they may not appear in the Packages files on various
8479 + feeds. Furthermore, one should be able to install from URL or
8480 + local storage without requiring a Packages file from any feed.
