Quicklook was written in IDL.  It allows astronomers to quickly perform minor analysis on data produced by the CSHELL spectrometer.  The software is simple to operate, requiring little user input but allowing maximum flexibility.  This software was successfully used at the NASA Infrared Telescope Facility during the apparition of Hale-Bopp.
