I guess the way to get this info is to parse both petscconf.h and<br>
petscvariables to pull out datatypes used in the binary files. The<br>
matlab scripts doing binary IO require you to know this ahead of time,<br>
but that seems a little silly when we should be able to get this info<br>
from the installation. I just assumed that all of this would be defined<br>
somewhere in petscvariables.<br>
