-
-   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
