Special thanks to those who have made valuable contributions (roughly in order of first contribution by date) Charles Doutriaux wrote the python wrapper for unit conversions with the UDUnits library (no longer used) Enthought Inc. the original units registry was developed at Enthought for the Enthought Tool Suite. John Salvatier added support for the Quantity iterator, contributed to support for simplified representations of units, comparison operators, and contributed unit tests. Tony Yu contributed several bug fixes and contributed to the documentation.
