        <!-- 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. -->
