" vim-plug: Vim plugin manager
" ============================
"
" Download plug.vim and put it in ~/.vim/autoload
"
" curl -fLo ~/.vim/autoload/plug.vim --create-dirs \
" https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim
"
" Edit your .vimrc
"
" call plug#begin('~/.vim/plugged')
"
" " Make sure you use single quotes
"
" " Shorthand notation; fetches https://github.com/junegunn/vim-easy-align
" Plug 'junegunn/vim-easy-align'
"
" " Any valid git URL is allowed
" Plug 'https://github.com/junegunn/vim-github-dashboard.git'
"
" " Multiple Plug commands can be written in a single line using | separators
" Plug 'SirVer/ultisnips' | Plug 'honza/vim-snippets'
"
" " On-demand loading
" Plug 'scrooloose/nerdtree', { 'on': 'NERDTreeToggle' }
" Plug 'tpope/vim-fireplace', { 'for': 'clojure' }
"
" " Using a non-default branch
" Plug 'rdnetto/YCM-Generator', { 'branch': 'stable' }
"
" " Using a tagged release; wildcard allowed (requires git 1.9.2 or above)
" Plug 'fatih/vim-go', { 'tag': '*' }
"
" " Plugin options
" Plug 'nsf/gocode', { 'tag': 'v.20150303', 'rtp': 'vim' }
"
" " Plugin outside ~/.vim/plugged with post-update hook
" Plug 'junegunn/fzf', { 'dir': '~/.fzf', 'do': './install --all' }
"
" " Unmanaged plugin (manually installed and updated)
" Plug '~/my-prototype-plugin'
"
" " Initialize plugin system
" call plug#end()

"| `branch`/`tag`/`commit` | Branch/tag/commit of the repository to use |
"| `rtp` | Subdirectory that contains Vim plugin |
"| `dir` | Custom directory for the plugin |
"| `as` | Use different name for the plugin |
"| `do` | Post-update hook (string or funcref) |
