+Pandas - a library for panel, time series, or cross-sectional data analysis
+===========================================================================
+
+Main data structures (see docstrings for detailed documentation)
+--------------------
+Index
+    Represent row or column labels in Series / DataFrame structures
+
+Series / TimeSeries
+    Represents standard 1-dimensional cross-section (resp. time series)
+    As an numpy.ndarray subclass, compatible with ufuncs and other NumPy
+    functions
+
+DataFrame / DataMatrix
+    Represent collections of Series objects, enable easy management
+    of multiple time series / cross-sections
+
+DateRange
+    Index subclass for generating arrays of fixed frequency dates
+    
+Subpackages
+-----------
+core
+    Implementations of core data structures, basic building blocks. Most of
+    the user-relevant code is accessible through the top-level namespace
+io
+    Persistence, parsing, and data loading tools
+lib
+    C, Cython, and Fortran extensions for other components
+stats
+    Standard
