Use the rename command, and you've got it. Another possibility is to have your build script split up the name and apply a custom sort order to it. The pattern is: "rw" + version number + suffix The suffices appear in this order: "dev", "alpha", "beta", "", "pat" (where not all appear, e.g. "dev" never appears for a minor release, and sometimes "alpha" is skipped).
