[NTG-context] invoices: make module or wikify

Hi, I'm writing my invoices like this: \environment e-invoice \beginInvoice \startInvItem[amount=123] bla bla 1 \stopInvItem \startInvItem[amount=456] bla bla 2 \stopInvItem \endInvoice If anybody is interested (e.g. for using it, making a module or wikifying), then I can send my files (no time to do it myself...) There are also calculations: \environment e-calculation \beginCalculation \startCalcItem[title=Title 1][hours=123] Do this and that, bla bla bla. \stopCalcItem \startCalcItem[title=Title 2][hours=456] Do something else, a lot of work. \stopCalcItem \endCalculation -- Peter
