Chapter 27 Custom Versions
An edition would be a copy of your project, different than one produced at some other time. For example, you might elect to make annual editions, with corrections, additions, and deletions. By contrast, a version is a copy of your project that shares content with another version, but differs in minor or substantial ways. We provide mechanisms for minor differences in Section 27.1 and for substantial differences in Section 27.2. Be sure to read about both mechanisms first, and understand their purposes, before committing to one or the other.
