Thanks, that clarified some remaining questions for me; this insight 
might be a good addition to the intro section of the scribble docs.

I guess, with careful planning,  you could use the ability to 
escape-to-scheme to generate documentation that is tailored to the 
actual installation, e.g. by replacing the generic installation paths 
used in the normal documentation with the actual paths of the installation?
