Where is expat in Slackware 15.0?

As I was installing Slackware 15.0 I noticed in the "terse" descriptions a package called expat which was described as an xml parser. As I have a need to parse/view XML files, I thought I'd try it. But, even though slackpkg says it's installed, I cannot find a man page on expat, nor an executable by that name.

So, does someone have an idea on how to use this?
