   The profiling package is an interactive continuous Python profiler.  It is
   inspired from `Unity 3D <http://unity3d.com/>`_ profiler.  This package
   provides these features:

   - Profiling statistics keep the frame stack.
   - An interactive TUI profiling statistics viewer.
   - Provides both of statistical and deterministic profiling.
   - Utilities for remote profiling.
   - Thread or greenlet aware CPU timer.
   - Supports Python 2.7, 3.3, 3.4 and 3.5.
   - Currently supports only Linux.
