   Jade does have some interesting file I/O capabilities via SP's
Formal System Identifiers, but no DSSSL implementation is appropriate
for file management.  DSSSL is a transformation and styling language,
not a shell.
   My suggestion would be to create a shell script or Makefile to wrap
around your Jade calls, and let these do the work.  If you want to do
file management based on information in your document, why not have
your stylesheet use (make entity) to write out a shell script that can
be run (possibly by another shell script that also invokes Jade) after
Jade has finished?  This automatically generated script could do all
of the needed directory creation and file copying.
   Of course, I'm assuming you're running under a unix-ish system.
If this is under Windoze, you'd need to cook up something a little
different, but the basic idea should be adaptable.
