      Neovim is a project that seeks to aggressively refactor Vim in order to:
      - Simplify maintenance and encourage contributions
      - Split the work between multiple developers
      - Enable the implementation of new/modern user interfaces without any
        modifications to the core source
      - Improve extensibility with a new plugin architecture
