a new list: sets.subr -- The set-listing code that is common to makeplist, makeflist, and regpkg has moved here. syspkgdeps -- Compute naive dependencies for system packages based on directory containment. I.e., if package A contains path /p/q, and package B contains path /p, then B is considered a dependency of A. As Jim Wise remarks, this is not quite right: system-package dependencies should indicate a functional dependency. Nevertheless, these naive dependencies protect us from orphaning files when pkg_delete'ing system packages. culldeps -- Helper for syspkgdeps. Removes redundant dependencies from a dependencies table. Essentially does the opposite of a transitive closure on a dependencies table: if the table contains A depends-on B, B depends-on C, and A depends-on C, then A depends-on C is removed because it can be derived from the prior two dependencies. deps -- Dependencies computed by syspkgdeps.
