Describe the new subcommands and how they should be used in a normal
workflow.
Note that the naming of branches is very rigid, or 'opinionated' in
marketing terms. Patman can track a single branch for each version of a
series and they must all be named the same, except for the
version-number suffix. Version 1 series have no suffix.
This description is fairly bare-bones but should be enough for some
initial testing and comments.
