# Blender.Ipo module and the Ipo PyType object

"""
The Blender.Ipo submodule

B{New}: Ipo updates to both the program and bpython acess.

This module provides access to the Ipo Data in Blender. An Ipo is composed of
several Ipocurves.

A datatype is defined : IpoCurve type. The member functions of this data type
are given below.


Example::
  import Blender
  ob = Blender.Ipo.Get('ipo')    # retrieves an ipo object
  ob.setName('ipo1')
  print ob.name
  print ipo.getRctf()
  ipo.setRctf(1,2,3,4)
