From TSC:

let's move this to a dedicated command: possible suggestions include wwctl overlay info (which could give us a place to also show docs) or wwctl overlay vars (for all vars) or wwctl overlay tags (if we are going to just show tags).

The output now looks like:

./wwctl --warewulfconf /etc/warewulf/warewulf.conf overlay variables ifcfg etc/sysconfig/network-scripts/ifcfg.ww

I have modified the template by adding {{/*$netdev.Tags.DNSSEARCH: domain in which the node resides */}} which will be used as help comment. I just don't know where to document this.
@anderbubble can you please review and boss someone around who adds the help comment tags for the next release.
