Comment # 4 on bug 917638 from Kristoffer Gronlund

Oh, I should say, the cluster scripts functionality I added to crmsh was meant
to eventually be able to implement the collection stuff in hb_report.

Right now, the cluster health command calls a cluster script which in turn
calls hb_report as part of its execution, but in theory it could do everything
that hb_report does by itself. Cluster scripts can be written in any language,
but right now the API that crmsh expects them to implement is somewhat
complicated.. I'm hoping that I can simplify that so that writing new cluster
scripts gets easier.

Since it's the first iteration of the idea and I was figuring out just what the
idea was while I was implementing it, the cluster scripts user interface is not
perfect. But I have some ideas for improving it which would make it a lot more
usable I think.
