" Remark: Uses HTML syntax file
" Remark: I don't do anything with angle brackets (<>) because that would too easily
" easily conflict with HTML syntax
" TODO: Do something appropriate with image syntax
" TODO: Handle stuff contained within stuff (e.g. headings within blockquotes)
" Read the HTML syntax to start with

so <sfile>:p:h/html.vim
