Could be done yet this is not our primary priority and also we are running
Tryton 3.0.2 due to certain modules holding us back. I'm sure upgrading
will still not resolve the issue as the old one must have the functionality
yet so how do I access these functions? what are they called? what is the
argument pass structure? I have seen some documentation here
(https://code.google.com/p/python-relatorio/wiki/QuickExample)
unfortunately maybe I myself have not come across the right documentation
for the library, yet so we need access to such functions and without a
reference there is little one can do. or
(http://sourcecodebrowser.com/relatorio/0.5.2/functions.html) yet so this
includes python functions and not underlying relatorio functions, maybe
these are called as python functions I do not know. Yet what I need is that
in the .odt where I put <invoice.date> i can do add_days(14, invoice.date).
