distinct parse-able structures whether local or remote, the existing directory
structure with multiple documents and document images etc. and git directories
with all content associated with a single document (including other language
versions of it); cannot guarantee at this stage that the file structure will be
retained, which may mean recreating any directory started and defeat the
purpose of using it, though it is in a version control repo, so perhaps not ...
