using the IIS site name to parameterize an ASP.NET application when deployed via MS Deploy

Question

Microsoft

I need to prepare a package for deploying an ASP.NET application via MS Deploy, which would use the name of the IIS site as one of the parameters.

To be precise, I need the application to be able to install only in the root of the IIS site and create a database for it, the name of which matches the name of the site.

What needs to be written in the parameters.xml file so that the name of the current site can be used to parameterize the application being installed?
