  11     -q --quiet                run silently; only print error msgs
  12     -v --verbose              be more verbose -- show misc extra info

  16     --trace-children-skip-by-arg=patt1,patt2,...   same as --trace-children-skip=
  17                               but check the argv[] entries for children, rather
  18                               than the exe name, to make a follow/no-follow decision

  23                               to get started quickly, use --vgdb-error=0
  24                               and follow the on-screen directions
