This is because the Accumulators docs have LaTeX formulas embedded in 
Doxygen comments directly in the C++ source code. The Accumulators 
reference section is built using Doxygen, which needs to invoke LaTeX to 
process the formulas, generate the images and link to them correctly.

I could generate the images by hand and check them in, but then as soon 
as someone modifies the Doxygen comments in my code, the links to the 
images would get out of whack, and the problem could be very subtle: 
different formulas showing up in the wrong places.
