virtuoso

[Petrus de Calguarium]

I notice that I do not have virtuoso-opensource-utils installed. I ran yum info 
virt-o-u... and all it tells me is that these are utilities.

What would this package do for me? What commands, functions does it provide? 
What is in it that I might actually like to use or would conceivably use?

How do I get yum to tell me the above in the future, without me having to ask 
on a forum (for similar future cases when I wish to know what a package 
actually does, since yum info barely ever really tells you much at all upon 
which to base a should I/should I not install question on)?
