Can zypper reveal what order it would install RPMs in?

I have set of home-grown RPMs that I'm trying to use zypper to install. They all have misc 'Requires' directives that I hoped would drive what order they are installed. I'm running into challenges wherein zypper seemingly is not honoring them; some are going in out-of-order. Is there are way of having zypper reveal dependency loops, and how it expects to solve them, without committing to an installation pass? -- Brian Reichert <reichert@numachi.com> BSD admin/developer at large
