The Australian tax invoice i hacked up can be had from this page:
	http://libertysys.com.au/gnucash/tax-invoice
I'd be happy for it to be included in future versions if anyone cares to
do so (i changed very little of it, so i didn't even bother copyrighting
my extensions).  It would be even better if it could be called "tax
invoice", rather than "fancy invoice", but when i tried to do that it
broke things.

Some of us are "decent software engineers" (hopefully - at least that's
what they pay me for), but can't spare a week to get this right.  The
last time i touched LISP was 1990, and in the CS faculty i trained under
(http://www.fit.qut.edu.au/), it was an afterthought, not an intro to CS
tool (QUT used Pascal at the time).  I suspect most university-trained
CS people in the last decade in .au have cut their teeth Pascal,
Modula-*, Java, or (God help us all) Visual Basic.  Sure, some of us can
hack and slash at it, but it's not anything like our native tongue.
It's like asking me to write poetry in German - i can't even write it in
English!  ;-)

Did you know?  If you use two dashes followed by a space as your
