There is already an excellent package for displaying equations on
TTYs.  It is called `eqnascii', written by Przemek Borys
<address@hidden>.  Unfortunately, I don't have time to integrate
this stuff into eqn.  And I must admit that my knowledge of the
internal details of eqn is very limited.  Any volunteers?
