However, the field maps depend on the version of the subroutine that reads
it. Similarly, the background simulation files won't change unless
somebody decides to make an improvement. There may be other files that are
fairly static. Should we put these under CVS ?
Or are they going to change so rarely that it's not worth the effort ?
