* the product integral symbol only exists in Computer Modern, therefore the code above is only valid when using this font
* this setup defines three commands: <code>\prodi</code> for inline formulae, <code>\Prodi</code> and <code>\PRODI</code> for displaystyle formulae (where the latter is slightly larger); see the sample file prodint.pdf in the archive for example usage
* '''IMPORTANT: the current settings disable font styles like boldface, italic, slanted, etc. This is an unresolved issue!!!'''
