+     "This package provides a flexible toolbox for observation planning and
+scheduling.  When complete, the goal is to be easy for Python beginners and new
+observers to to pick up, but powerful enough for observatories preparing nightly
+and long-term schedules.
+
+Features:
+@itemize
+@item calculate rise/set/meridian transit times, alt/az positions for targets at
+observatories anywhere on Earth
+@item built-in plotting convenience functions for standard observation planning
+plots (airmass, parallactic angle, sky maps)
+@item determining observability of sets of targets given an arbitrary set of
+constraints (i.e., altitude, airmass, moon separation/illumination, etc.)
