示例1: _addSharedImportsToShell

    console.assert(this.shell != null);
    let shellDeps = bundles.get(this.shell)
        .map((d) => path.relative(path.dirname(this.shell), d));

    let file = this.analyzer.files.get(this.shell);

    let doc = dom5.parse(contents);
    let imports = dom5.queryAll(doc, dom5.predicates.AND(
      dom5.predicates.hasTagName('link'),
      dom5.predicates.hasAttrValue('rel', 'import')
    ));

    // Remove all imports that are in the shared deps list so that we prefer
    // the ordering or shared deps. Any imports left should be independent of
    // ordering of shared deps.
