An IRAF-based processing pipeline has been written to reduce spectra, keeping the maximum wavelength precision, which varies from 0.03 to 0.07 Angstroms/pixel over 51 orders covering a range of 3850 to 9100 Angstroms. The same software which is used at the telescope for quick-look real-time processing can be used with relatively few parameter changes to produce data with more accuracy for scientific processing. Important features are portability and simplicity, so that scientists can re-reduce their data in various ways to optimize its quality for their needs. The use of a legacy of relevant software from both NOAO and SAO IRAF packages has made the task easier.
