Newbie question: Adding "labels"

[David Wilson]

First off, thanks for making such a great product in MapServer. Really
enjoying it.

I think I'm having a jargon problem. I can't figure out if the data I
have contains labels (for example highway numbers) and how to get
MapServer to display them.

In the mapfile reference, I expect "label" to refer to the thing I'm
looking for, but that seems to refer to text manually inserted in the
map file.

How do I determine if the names are included in the shapefile data?
How do I display the names with MapServer?

Thanks!
Dave
