-neovim-remote
-=============
-
-**nvr** is a tool that helps controlling nvim processes.
-
-It basically does two things:
-
-1. adds back the ``--remote`` family of options (see ``man vim``)
-2. helps controlling the current nvim from within ``:terminal``
-
-To target a certain nvim process, you either use the ``--servername`` option or
-set the environment variable ``$NVIM_LISTEN_ADDRESS``.
-
-Since ``$NVIM_LISTEN_ADDRESS`` is implicitely set by each nvim process, you can
-call **nvr** from within Neovim (``:terminal``) without specifying
-``--servername``.
