How-to
Task-oriented. Reconcile a release against the previous one with
code-update, or start codes from scratch with code-create for
a first release, then check them with code-detect.
Codes
Fourth step of boundary cleaning. This step gives every unit a code: its code from the previous release where the unit carries over, and a new one where it doesn’t.
Reference
Information-oriented. What code-detect, code-create,
code-update and change do, with their options and outputs.
