The IGRINS (Immersion Grating Infrared Spectrometer) PipeLine Package (PLP) processes all IGRINS observing data, such as that from the McDonald 2.7m, LDT/DCT, or Gemini-South telescopes, without (or with a minimum of) human interaction. It was also designed to be adaptable for a real time processing during the observing run. The IGRINS PLP uses a "recipe" to process a certain data group and requires an input file describing which recipe should be used with which data sets.
