        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
