[petsc-dev] raise ValueError in check_for_option_mistakes

[Satish Balay]

Matt,

raise ValueError in check_for_option_mistakes() is not trapped by any
error handler. Any idea if this code can be reorganized so that
ValueError from check_for_option_mistakes() doesn't give a stack? [if
not I can do print(message)/exit(2) for this routine]

thanks,
satish
