My attempt at a simple `.vimrc` file with the aim to have sensible defaults.

.vimrc

" Disable vi compatibility so we can use cool vim stuff:
set nocompatible

" Line numbers (left hand side)  and position (bottom right):
set ruler
set number

" Highlight current line:
set cul

" Filetype aware:
filetype plugin on
filetype indent on

" Syntax highlighting:
syntax on

" We don't need backup files:
set nobackup
set nowb
set noswapfile

" Set tabs to 4 spaces
set tabstop=4
set shiftwidth=4
