title: How do I "source" something in my .vimrc file?
body: <p>I've been working on expanding my vim-foo lately and I've run across a couple of plugins (<a href="http://www.vim.org/scripts/script.php?script_id=1343" rel="noreferrer">autotag.vim</a> for example) that require them to be "sourced" in my .vimrc file. What exactly does this mean and how do I do it?</p>
