This talk will cover the essential mechanics of dep, combined with an explanation of the main ideas behind dep’s design. It makes sense to explain these together, as dep is an opinionated tool with a spare interface: if people don’t understand dep’s basic way of thinking about dependency management, then they may find themselves “holding it wrong,” and having a difficult time. The benefit of dep’s spare design is that doesn’t take long to cover the essentials, and attendees will be able to walk away with a clear sense of how to leverage dep to their advantage.
