 If you would like to add support for writing a language with PipeScript, this is the place to put it.
 
 Transpilers in this directory should:
-* Be named ```Inline.NameOfLanguage.psx.ps1```.
-* Accept ```[Management.Automation.CommandInfo]``` as a pipeline parameter.
-* Use ```[ValidateScript({})]``` or ```[ValidatePattern()]``` to ensure that the correct file type is targeted.
+* Be named `NameOfLanguage.Template.psx.ps1`.
+* Accept `[Management.Automation.CommandInfo]` as a pipeline parameter, in it's own parameter set
+* Accept `[switch]$AsTemplateObject` as a mandatory parameter in it's own parameter set.
+* Use `[ValidatePattern()]` to ensure that the correct file type is targeted.
 
-Each file should handle one and only one language (better explicit than terse).
+The template transpiler will then create a set of parameters to PipeScript.Template.
 
-Transpilers should call ```.>PipeScript.Inline``` to simplify and standarize processing.
+If $AsTemplateObject is passed, these parameters should be returned directly.
+Otherwise, the template transpiler should call ```.>PipeScript.Template```.
