                <!-- NOTE: Most of the following excludes should not be required
                     if the standard release process is followed. This is because the
                     release plugin checks out project sources into a location like
                     target/checkout, then runs the build from there. The result is
                     a source-release archive that comes from a pretty clean directory
                     structure.

                     HOWEVER, if the release plugin is configured to run extra goals
                     or generate a project website, it's definitely possible that some
                     of these files will be present. So, it's safer to exclude them.
