[Paraview] simple vs servermanager python module

[Anton Shterenlikht]

In my paraview book (2007) python scripting chapter
always refers to servermanager module.

In this (presumably much more recent) python tutorial:
http://www.paraview.org/Wiki/ParaView/Python_Scripting
the reference is always to module "simple", however,
lines like this are confusing:

*quote*
When using a Mac to use the build tree in IDLE, start by loading the servermanager module:

>>> from paraview.simple import *

Note: Importing the paraview module directly is deprecated, although still possible for backwards compatibility. This document refers to the simple module alone. 
*end*

So which is it, servermanager or simple?

I'm still on paraview 3.10 and 3.12.

Thanks

Anton
