I emailed Paul Johnson a week or so back and offered to help him clarify the docs on Devel::Cover, because $DEITY knows they confuse me enough, and I've been using DC for years.
So the plan is to generally edit/improve what's there, including Devel::Cover::Tutorial (did you know that existed?) and to add a Devel::Cover::Cookbook giving examples of common uses of DC. It'll cover things like "running DC from make test" and "excluding unwanted files" and so forth.
So my question to you, gentle readers, is do you have any questions you'd like answered or tips you'd like to share in the docs? If so I'll try and cover them.
