The goal of completeme is to help me, help you. It allows package authors and users to register a set of completion functions to define custom completions.

Package authors can define custom completions for their package and register them with completeme in .onLoad().

.onLoad <- function(pkg, lib) {
  completeme::register_completion(mypackagename = completion_function)
}

Name inspired by YouCompleteMe and Maverick.
