 ARC Echelle Spectroscopic Observation Pipeline (aesop)
+
+
+The ARC Echelle Spectroscopic Observation Pipeline, or ``aesop``, is a high resolution 
+spectroscopy software toolkit tailored for observations from the Astrophysics Research 
+Consortium (ARC) Echelle Spectrograph mounted on the ARC 3.5 m Telescope at Apache 
+Point Observatory. ``aesop`` picks up where the traditional IRAF reduction scripts leave 
+off, offering an open development, object-oriented Pythonic analysis framework for echelle
+spectra. 
+
+Basic functionality of ``aesop`` includes: (1) blaze function normalization by polynomial 
+fits to observations of early-type stars, (2) an additional/alternative robust least-squares 
+normalization method, (3) radial velocity measurements (or offset removals) via 
+cross-correlation with model spectra, including barycentric radial velocity calculations, 
+(4) concatenation of multiple echelle orders into a simple 1D spectrum, and (5) approximate
+flux calibration.
