But as it is currently implemented, the script simply prints out `\0` delimited package names. So one UI wart is `--extra-prebuild-script` being a somewhat generic name but that script only emits package names. `--extra-packages-script` would be a better name.
  The script also has to install packages into the virtualenv so they're findable.

  I'm open to having both an --extra-package *and* a script argument, if that's what you're proposing. Does that sound workable?
