'''
This module will:
- change the input() and raw_input() commands to change \r\n or \r into \n
- execute the user site customize -- if available
- change raw_input() and input() to also remove any trailing \r
Up to PyDev 3.4 it also was setting the default encoding, but it was removed because of differences when
running from a shell (i.e.: now we just set the PYTHONIOENCODING related to that -- which is properly
treated on Py 2.7 onwards).
