I am aware of it but had the impression that it expects a Dabo bisobj, 
could I use it with using SQLAlchemy to access my database? I.e. feed it 
a SQLAlchemy query and access relations to get at columns?

e.g.:
result = session.query(db.Winerack)

for r in result:
     print r.name
     for u in r.wineracku:
         print u.description
         for b in u.winerackb:
             print b.description, b.binno
             for i in b.winerackit:
                 print i.subbinno
                 if i.bottag:
                     print i.bottag[0].cellarbook.drinkinfo.name


the "for" loops would be groups and the last one would be the detail 
level which might need one or more lines.  In some of the reports the 
"more lines" would be large text blob column which is the one which 
might need to span over multiple pages.
