Algorithms - A set of misc algorithms
see all of the effects of an upgrade run.
pkgDistUpgrade computes an upgrade that causes as many packages as
- possible to move to the newest verison.
+ possible to move to the newest version.
pkgApplyStatus sets the target state based on the content of the status
field in the status file. It is important to get proper crash recovery.
