+ /**
+ * mw.Upload.BookletLayout encapsulates the process of uploading a file
+ * to MediaWiki using the {@link mw.Upload upload model}.
+ * The booklet emits events that can be used to get the stashed
+ * upload and the final file. It can be extended to accept
+ * additional fields from the user for specific scenarios like
+ * for Commons, or campaigns.
+ *
+ * ## Structure
+ *
+ * The {@link OO.ui.BookletLayout booklet layout} has three steps:
+ *
+ * - **Upload**: Has a {@link OO.ui.SelectFileWidget field} to get the file object.
+ *
+ * - **Information**: Has a {@link OO.ui.FormLayout form} to collect metadata. This can be
+ * extended.
+ *
+ * - **Insert**: Has details on how to use the file that was uploaded.
+ *
+ * Each step has a form associated with it defined in
+ * {@link #renderUploadForm renderUploadForm},
+ * {@link #renderInfoForm renderInfoForm}, and
+ * {@link #renderInsertForm renderInfoForm}. The
+ * {@link #getFile getFile},
+ * {@link #getFilename getFilename}, and
+ * {@link #getText getText} methods are used to get
+ * the information filled in these forms, required to call
+ * {@link mw.Upload mw.Upload}.
+ *
+ * ## Usage
+ *
+ * See the {@link mw.Upload.Dialog upload dialog}.
+ *
+ * The {@link #event-fileUploaded fileUploaded},
+ * and {@link #event-fileSaved fileSaved} events can
+ * be used to get details of the upload.
+ *
+ * ## Extending
+ *
+ * To extend using {@link mw.Upload mw.Upload}, override
+ * {@link #renderInfoForm renderInfoForm} to render
+ * the form required for the specific use-case. Update the
+ * {@link #getFilename getFilename}, and
+ * {@link #getText getText} methods to return data
+ * from your newly created form. If you added new fields you'll also have
+ * to update the {@link #clear} method.
+ *
+ * If you plan to use a different upload model, apart from what is mentioned
+ * above, you'll also have to override the
+ * {@link #createUpload createUpload} method to
+ * return the new model. The {@link #saveFile saveFile}, and
+ * the {@link #uploadFile uploadFile} methods need to be
+ * overridden to use the new model and data returned from the forms.
+ *
+ * @class
+ * @extends OO.ui.BookletLayout
+ *
+ * @constructor
+ * @param {Object} config Configuration options
+ * @cfg {jQuery} [$overlay] Overlay to use for widgets in the booklet
+ * @cfg {string} [filekey] Sets the stashed file to finish uploading. Overrides most of the file selection process, and fetches a thumbnail from the server.
