+" let filetype_m="mma"
+"
+" I also recommend setting the default 'Comment' hilighting to something
+" other than the color used for 'Function', since both are plentiful in
+" most mathematica files, and they are often the same color (when using
+" background=dark). I use

+" hi Comment ctermfg=darkcyan
+"
+" darkgreen also looks good on my terminal.
