-
- The 3 version fields should go into a single version struct. (This
- is especially important since, currently, pkg->version can easily
- be mistaken for pkg_verson_str_alloc(pkg) although they are very
- distinct. This has been the source of multiple bugs.
-
- The 3 state fields could possibly also go into their own struct.
-
- All fields which deal with lists of packages, (Depends,
- Pre-Depends, Provides, Suggests, Recommends, Enhances), should each
- 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,
- but probably not since most often we only create new pkg_t structs,
- we don't often free them. */
