- 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.

- be handled by a single struct in pkg_t
-
- All string fields for which there is a small set of possible
- values, (section, maintainer, architecture, maybe version?), that
- are reused among different packages -- for all such packages we
- should move from "char *"s to some atom datatype to share data
- storage and use less memory. We might even do reference counting,
