Program Evolution

How do we make best use of an up-to-date program and outdated documentation?

How do we document the evolution of the program?

It is possible to process several versions of a source program together with one version of the documentation
Automatic bookkeeping of fine grained program evolution steps
- New, deleted, moved, renamed abstractions
- Extensive crosslinking of program versions
Possible to address both new and old versions of abstractions from the documentation
- Provides for documentation of the program evolution
