Visualizing the startup order

[shdwrnnr]

Is there a way to preview the order that the services are going to end up starting in? My reasoning is that it would be nice to be able to run a script and quickly be able to see what services need to be shifted around using the use, need, after, and before features (without having to either reboot or initiate an actual runlevel change). If this isn't possible, I can probably look into hacking up depscan.sh (if even appropriate) to do something like this.
