Hello,

I'm trying to build a template for invoices written in Org... exporting
to PDF (and HTML). Will be officially public as soon as it's DONE.

Though, I have 2 problems currently:

- I'd like to sum up, in table `total', the sub-total column of table
  `items'. But the `remote' call does not seem to accept the `vsum'
  expression. Is this a foreseen limitation?  Is there a workaround to this?

- I'd like to get the computed amount (last line of `total' table) in bold (and,
  if possible, even in a bigger font). How is that doable?
