The command
texput(tildepsi,"\\tilde \\psi")
will do that.

Not hard at all, once a convention for writing the upper case
variables is made. Since Maxima is currently case insensitive,
psi and Psi are indistiguishable. It would be easy to make something
like CapitalPsi TeX up as \Psi.
Since Maxima may become case sensitive, it may be better to wait to do
something extensive about this, and just use texput as needed for
right now.

So, for a cell like
\beginmaxima
2+2;
\maximatexoutput
\m 4 \\
\endmaxima
the
2+2;
should be TeXed, but not the 4. Right?

It'd have to do a bit more, since emaxima.sty defines some TeX
commands that are used in a cell.
So the script would have to have a cell like
\beginmaximasession
2+2;
\maximatexsession
\C4. 2+2; \\
\D4. 4 \\
\endmaximasession
and replace it by
%\beginmaximasession
%2+2;
%\maximatexsession
%\C4. 2+2; \\
%\D4. 4 \\
%\endmaximasession
(C4) \verb~2+2;~ \\
(D4) \[ 4 \]
(something better than that, actually, but you get the idea.)
For normal cells, like the 2+2; one above, it'd be different.
As a starting point, what kind of cells would be most useful?
