   4          * mw.Upload.BookletLayout encapsulates the process of uploading a file
   5          * to MediaWiki using the {@link mw.Upload upload model}.
   6          * The booklet emits events that can be used to get the stashed
   7          * upload and the final file. It can be extended to accept
   8          * additional fields from the user for specific scenarios like
   9          * for Commons, or campaigns.
  10          *
  11          * ## Structure
  12          *
  13          * The {@link OO.ui.BookletLayout booklet layout} has three steps:
  14          *
  15          *  - **Upload**: Has a {@link OO.ui.SelectFileWidget field} to get the file object.
  16          *
  17          * - **Information**: Has a {@link OO.ui.FormLayout form} to collect metadata. This can be
  18          *   extended.
  19          *
  20          * - **Insert**: Has details on how to use the file that was uploaded.
  21          *
  22          * Each step has a form associated with it defined in
  23          * {@link #renderUploadForm renderUploadForm},
  24          * {@link #renderInfoForm renderInfoForm}, and
  25          * {@link #renderInsertForm renderInfoForm}. The
  26          * {@link #getFile getFile},
  27          * {@link #getFilename getFilename}, and
  28          * {@link #getText getText} methods are used to get
  29          * the information filled in these forms, required to call
  30          * {@link mw.Upload mw.Upload}.
  31          *
  32          * ## Usage
  33          *
  34          * See the {@link mw.Upload.Dialog upload dialog}.
  35          *
  36          * The {@link #event-fileUploaded fileUploaded},
  37          * and {@link #event-fileSaved fileSaved} events can
  38          * be used to get details of the upload.
  39          *
  40          * ## Extending
  41          *
  42          * To extend using {@link mw.Upload mw.Upload}, override
  43          * {@link #renderInfoForm renderInfoForm} to render
  44          * the form required for the specific use-case. Update the
  45          * {@link #getFilename getFilename}, and
  46          * {@link #getText getText} methods to return data
  47          * from your newly created form. If you added new fields you'll also have
  48          * to update the {@link #clear} method.
  49          *
  50          * If you plan to use a different upload model, apart from what is mentioned
  51          * above, you'll also have to override the
  52          * {@link #createUpload createUpload} method to
  53          * return the new model. The {@link #saveFile saveFile}, and
  54          * the {@link #uploadFile uploadFile} methods need to be
  55          * overridden to use the new model and data returned from the forms.
