hello.sgml is a sample file I grabbed from the tutorial on
how to use DocBook at the following address:

  http://nis-www.lanl.gov/~rosalia/mydocs/docbook-intro/docbook-intro.html

I left it as-is, since I don't yet know how to use DocBook,
and I wanted something that would exercise the required tools.
It belongs to it's respective creator, and is not licensed
under the GNU FDL as are many of the other files.
