| 4 | | - * SF_UploadWindow - used for uploading files from within a form, for |
| 5 | | - * versions of MediaWiki below 1.16. |
| 6 | | - * This class is nearly identical to the pre-1.16 version of MediaWiki's |
| 7 | | - * SpecialUpload class, but with a few changes to remove skin CSS and |
| 8 | | - * HTML, and to populate the relevant field in the form with the name |
| 9 | | - * of the uploaded form. |
| 10 | | - * |
| 11 | | - * This class is based almost entirely on the upload functionality |
| 12 | | - * developed by the Chickipedia.com team. |
