+

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