8506 + can be found in th available file.

8509 + reconstruct a .ipk from an installed package, (ie. for beaming
8510 + from one handheld to another). So, maybe we actually want a few
8511 + more fields here, (depends, suggests, etc.), so that that would
8512 + be guaranteed to work even in the absence of more information
8513 + from the available file.
8514 +
8515 + 28-MAR-03: kergoth and I discussed this yesterday. We think
8516 + the essential info needs to be here for all installed packages
8517 + because they may not appear in the Packages files on various
8518 + feeds. Furthermore, one should be able to install from URL or
8519 + local storage without requiring a Packages file from any feed.

11056 + be mistaken for pkg_verson_str_alloc(pkg) although they are very
11057 + distinct. This has been the source of multiple bugs.
11058 +
11059 + The 3 state fields could possibly also go into their own struct.
11060 +
11061 + All fields which deal with lists of packages, (Depends,
11062 + Pre-Depends, Provides, Suggests, Recommends, Enhances), should each
11063 + be handled by a single struct in pkg_t
11064 +
11065 + All string fields for which there is a small set of possible
11066 + values, (section, maintainer, architecture, maybe version?), that
11067 + are reused among different packages -- for all such packages we
11068 + should move from "char *"s to some atom datatype to share data
11069 + storage and use less memory. We might even do reference counting,
11070 + but probably not since most often we only create new pkg_t structs,
