NDoc is truly an amazing library.

You can easily define your own documentation renderer (Documenter) class by implementing the NDoc.Core.IDocumenter interface (inheriting from BaseDocumenter will help). Once this is done, put the assembly ( named NDoc.Documenter.YourRenderer.dll) into the directory where NDocGUI.exe is and it will be loaded by Reflection where the GUI opens.

Since NLiterate is one way of looking at documentation, it deserved it's own documenter. The task was surprinsgly easy... maybe this could be my 2cents for NDoc :)
