Yes, the description includes, "This utility makes it possible to build your own
personal Debian package of Google Earth. The packaging itself is Free Software
..."

Calling it a utility and software leads me to believe that it is a program (to
automate the installation of Google Earth). Am I misinterpreting the
description?

If there is a build command needed, it is not mentioned in the description, so
I'm at a loss how to proceed.
