-+	can be found in th available file.
-+
-+	But, someone proposed the idea to make it possible to
-+	reconstruct a .ipk from an installed package, (ie. for beaming
-+	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.

-+   This function could be considerably simplified if we just kept
-+   an array of all the generic string-valued field names, and looped
-+   through those looking for a match. Also, these fields could perhaps
-+   be stored in the package as an array as well, (or, probably better,
-+   as an nv_pair_list_t).
-+
-+   Fields which require special parsing or storage, (such as Depends:
-+   and Status:) could be handled as they are now. 
-+*/
-+/* XXX: FEATURE: The Suggests: field needs to be changed from a string
-+   to a dependency list. And, since we already have
-+   Depends/Pre-Depends and need to add Conflicts, Recommends, and
-+   Enhances, perhaps we could generalize all of these and save some
-+   code duplication.
