''' 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).
