  Across an aggregation of EuSpRIG presentation papers, two maxims hold true:
spreadsheets models are akin to software, yet spreadsheet developers are not
software engineers. As such, the lack of traditional software engineering tools
and protocols invites a higher rate of error in the end result. This paper lays
ground work for spreadsheet modelling professionals to develop reproducible
audit tools using freely available, open source packages built with the Python
programming language, enabling stakeholders to develop clearly defined model
"oracles" with which to test and audit spreadsheet calculations against.
