98 be mistaken for pkg_verson_str_alloc(pkg) although they are very
99 distinct. This has been the source of multiple bugs.
101 The 3 state fields could possibly also go into their own struct.
103 All fields which deal with lists of packages, (Depends,
104 Pre-Depends, Provides, Suggests, Recommends, Enhances), should each
105 be handled by a single struct in pkg_t
107 All string fields for which there is a small set of possible
108 values, (section, maintainer, architecture, maybe version?), that
109 are reused among different packages -- for all such packages we
110 should move from "char *"s to some atom datatype to share data
111 storage and use less memory. We might even do reference counting,
112 but probably not since most often we only create new pkg_t structs,
113 we don't often free them. */
