val reduce : t -> t

Reduces a graph of atomic or concrete actions (only removals, installs and builds) by turning removal+install to reinstalls or up/down-grades, best for display. Dependency ordering won't be as accurate though, as there is no proper ordering of (reinstall a, reinstall b) if b depends on a. The resulting graph contains at most one action per package name.

There is no guarantee however that the resulting graph is acyclic.

val explicit : t -> t

Expand install actions, adding a build action preceding them.
