+Python.
+
+The following subpackages are available:
+@itemize
+@item funcFit: A convenient fitting package providing support for minimization
+and MCMC sampling.
+@item modelSuite: A Set of astrophysical models (e.g., transit light-curve
+modeling), which can be used stand-alone or with funcFit.
+@item AstroLib: A set of useful routines including a number of ports from
+IDL's astrolib.
+@item Constants: The package provides a number of often-needed constants.
+@item Timing: Provides algorithms for timing analysis such as the Lomb-Scargle
+and the Generalized Lomb-Scargle periodogram
+@item pyaGUI: A collection of GUI tools for interactive work.
