Create a .pnp file from a directory

I would like to source control an XML provisioning engine template and all of its required assets (js, css, html, etc.) in a Visual Studio project. When the time comes to provision the site, Id like to hand off a .pnp file that was generated from my project. I know I could apply the template to a site using the .xml, then extract a new .pnp from the site, but I would like to simplify this and eliminate the site from this process. Is this possible? If so, how?
