Thank you for your reply.  I have now modified the context engine to:

             ;; Insert User customization
             (let ((s (engine-custom e 'user-style)))
               (if s (format #t "\\input ~a\n" s)
             ;; Load Style - default is book
                     (format #t "\\input context-~a.tex\n"
                      (engine-custom e 'document-style))
                   ))

The user can get a context document by providing context customisations
in "context-book.tex" or in some '*.tex' file if they use skribilo's
user-style option.  I made a few other changes too and have been able to
generate compilable context files.

A possible improvement would be to have skribilo _write_ the default
context customisation file "context-book.tex" but I don't know how to do
this because I don't know much Guile.

I am working on getting skribilo to read org-mode syntax.  I want to be
able to write a document in org-mode and transform it to context (or
other format).  I am using a clone of the outline reader as a starting
point.

I have a question about getting from the outline format to the full
skribilo document format.  I can see there might be circumstances where
I begin a document in outline mode (or org mode) but transform it to the
full skribilo format for final editing.  I saw the question about this
on the mailing list but did not understand the answer.

Best wishes,
Roger
