setupNeovimPluginsWindows.py

#!/usr/bin/env python
"""
Sets up Neovim in windows

Prerequisites:
1) git needs to be installed
2) PLUG_MANAGER set to something (Ie. vim-plug, etc.)
3) INIT_VIM_LOCATION points to init.vim at some git repo
4) Might need to turn on developer options in Windows 10 so that symbolic links work!

Steps:
1) download desired release from https://github.com/neovim/neovim/releases
2) I extract files into c:/tools/Neovim
3) run this script!
