[O] Help with new exporter

[John Rakestraw]

Greetings, list --

I've been using Philip Hirschhorn's exam documentclass 
(http://www-math.mit.edu/~psh/#ExamCls) for several years to produce my 
exams. I've been writing the exams in org-mode and using the exporter to
produce the pdf.

I've recently moved to org 8.0. (I like it!) I've successfully 
converted all of my other export class definitions, but I can't figure 
out how to define the exam class so that I can export my exams. I've 
pasted below the class definition that worked with the previous exporter 
(I know it's clumsy, but it worked) and also a sample version of what I 
need in the tex file.

(I know I could just write the tex file directly, but it's nice to have 
all of the course materials included in human-readable form in the 
course org file.)

My problem is that I can't get the exporter to produce chunks like 
this:

\begin{questions}
\question
A paragraph describing how the students should answer the following 
questions.
\begin{parts}
\part
A multi-line question
\part
Another multi-line question
\end{parts}
\end{questions}

Thanks for whatever advice anyone can offer.

\begin{questions}
\question
Short Answer. A paragraph describing how I want students to respond to 
the
following questions. I want to leave vertical space filled with dotted 
lines
between the questions, and I want two questions on each page.
\begin{parts}
\part
This is the first question. It will be several lines long, so I'm 
writing enough
filler here to add at least a second line.
\fillwithdottedlines{\fill}
\part
This is the second question. It will also be several lines long, so I 
need
filler enough to get to the second line for this example.

\begin{questions}
\question
Essay Question. This is a section of essay questions. Students will 
answer only
one of these questions, so I don't need to leave space between the two 
questions.
\begin{parts}
\part
The first of the essay questions goes here. It will be several lines 
long, so I
want enough text in the example to provide a line break.
\part
The second essay question. It is also several lines long, so I'll add 
some
rambling text here for the second line.
