Reading further I see that I can export is QSF-XML format, which looks to be
about what I want for exporting data.  I then found a set if discussions about
using QSF to import Palm data (Neil Williams seems to be involved), and
that talked about importing invoices using QSF format, but I can not find
how to do the import.  The File->Import menu has QIF, OFX (which is good
as my bank uses OFX to export statement data), CSV or GnuCash log files, 
but nothing about QSF files.
