    \title Scanner Item
    \brief Creates custom dependency scanners in modules.

    A \c Scanner item can appear inside a \l{Module Item}, and allows to extract
    dependencies for artifacts from the artifacts' file contents.
    For example, this is what a scanner for "qrc" files might look like:
    \code
    import qbs.Xml

    Module {
      Scanner {
        inputs: 'qrc'
        scan: {
          var xml = new XmlDomDocument(input.filePath);
          dependencies = [];
          // retrieve <file> entries from the XML document
          return dependencies;
        }
      }
    }
    \endcode
