Manifest File ?

A Revit API manifest file is an XML file used to register add-ins with Autodesk Revit. This file contains information about the add-in, such as its name, class, location, and other metadata. When Revit starts, it reads these manifest files to load and integrate the add-ins into the Revit environment.
