+ClickOnce signing, also called _manifest signing_, is a method used for ClickOnce applications and Microsoft Office Add-ins created using Visual Studio Tools for Office (VSTO). Using `<clickonce-sign>` is equivalent to using Microsoft's `mage.exe`.
 
 ClickOnce signing applies to directories, not to individual files. Therefore, you need to specify a `<directory>` element for this method. If you want to sign files in the root directory of a container, specify `path="."`.
