I've grep'ed fairly thoroughly through the source, and I can't find
anything obviously wrong. business-core.i includes gncTaxTable.h, which
has the line
GList *gncTaxTableGetEntries (const GncTaxTable *table);
Is there anywhere else that defines the SWIG wrapper?
I'd like to be able to include details of the tax (specifically VAT)
charged on each line of the invoice, e.g.
Description Qty VATrate UnitPrice VAT Total
Book 1 0% £20.00 £0.00 £20.00
Computer 1 15% £100.00 £15.00 £115.00
