Is there a package for mathml fonts?

[Hendrik Boom <hendrik@topoi.pooq.com>]

At http://www.mozilla.org/projects/mathml/fonts/
it tells me 

> On Linux with Xft-enabled builds, you should install the TrueType TeX
> fonts and Mathematica 4.1 fonts (repeat: 4.1). To install TrueType fonts,
> simply extract and copy the .ttf files in your ~/.fonts/ directory

Now I suppose I can just follow these instructions and I'll have the
fonts myself. But is there a way to make thise fonts available to
*everybody* on my system?  Can they be installed as one or more Debian
packages?
