 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
 For lots more details, see the wiki!
