;; Fancy Invoice customized from "invoice.scm"
;; Customized by:  Oliver Jones <gnucash at oliverstech dot com>
;;
;; WARNING: customizations are hard-coded, some translations might be
;; broken and it won't work for bills/expense vouchers
;;
;; Customizations are marked with "oli-custom".
;;
;; Hint: you may set your default options here until a way to save report
;; options will be implemented.
;;
;; You will need to upgrade to gtkhtml-1.1 for the latest features or
;; it won't look right.  gtkhtml doesn't have support for table
;; colgroup, tbody, thead and rules tags yet. When it will, the
;; invoice will look even better.
;;
;; This is a quick and dirty hack. The proper way to do this (when I
;; or someone else will have time) is to have the user supply an HTML
;; template. The most common used templates will be distributed with
;; gnucash.

;; Modifed to use settable options instead of the hard coded ones.
;; modified by Brian Dolbec <dol-sen at telus dot net> Feb. 6, 2006
