Out of the box PackageManager should support anything that can be packaged as an .msi file and it lets you write plug-ins to handle just about any other type of method for packaging and distributing apps.
At the moment it's however largely a case of Microsoft quietly developing a quite powerful tool and then going out of their way to not tell anybody about it. Microsoft has also not shown any interest in developing and supporting their own general software repo (I guess they don't want to compete with their app store). So we've basically got to wait for third party developers to fill the cap. Fortunately the people behind chocolaty are working on this and have said they'll have something ready by Summer 2016.
