Loading Templates From Files

In Lift 3.0:

import net.liftweb.http.Templates._

val myTemplate: Box[NodeSeq] = Templates("some" :: "template" :: "path" :: Nil)

If you want to process the template for snippets, you can use S.runTemplate. See Instant Lift Web Applications How-To

Earlier versions of Lift used a TemplateFinder object:

You can load templates from files, perhaps when making your own responses, with TemplateFinder.findAnyTemplate.

It can be used to customize the ProtoUser screens using templates loaded from a file; just override loginXhtml and other xxxXhtml functions.
