| This is a simple class that can load, save, and remove |
| files from the native file system. It is needed by Safari and Opera |
| for the dojo.storage.browser.FileStorageProvider, since both of |
| these platforms have no native way to talk to the file system |
| for file:// URLs. Safari supports LiveConnect, but only for talking |
| to an applet, not for generic scripting by JavaScript, so we must |
| have an applet. |
