Default Packages for DMRAID Eventing posted to Redhat wiki page

Hi everyone,

Alasdair pointed me to a wiki that is hosted by Redhat that I could post
my eventing code on. I've made a page called DMRAID_Eventing:
http://sources.redhat.com/lvm2/wiki/DMRAID_Eventing

I would appreciate feedback on the wiki page (don't be too rough on me
since it's my first attempt at a wiki page). Also any feedback from
people trying out the eventing packages would be greatly appreciated.

Thanks,

Brian Wood
