 20:   the new method, after the current list.

 22:   Restricting the choices: To prevent all of the methods from being
 23:   registered and thus save memory, copy this routine and modify it to
 24:   register a zero, instead of the function name, for those methods you
 25:  do not wish to register.  Make sure that the replacement routine is
 26:   linked before libpetscmat.a.
