Convenince labels added to the top of each file to assist in creating
index-type help files for things like the XML editor screen (where
there's nothing to hook help to).

13: When creating randomized problems, you want to make sure that the problems
14: always have an answer. Consider what might happen if I had chosen the two
15: slopes \emph{both} with the expression \texttt{\&random(-1.0,1.0,.2)}. One
16: out of ten students would get a problem where both slopes were equal, which
17: has either no solution (for unequal y-intercepts) or an infinite number of
18: solutions (for equal slopes and y-intercepts). Both of these cause a division-by-zero
19: error on the division that computes the answer. There are many ways to avoid
20: this, one of the easiest of which is picking one slope negative and one positive.
21: This same problem can show up in many other places, too, so be careful.
