WARNING:
Usage of smesh.py is deprecated in SALOME V7.2!
smesh.py will be removed in a future version!
TODO:
The following changes in your scripts are required to avoid this message:

replace 
-------

import smesh, SMESH
smesh.SetCurrentStudy(theStudy)

with
----

import SMESH
from salome.smesh import smeshBuilder
smesh = smeshBuilder.New(salome.myStudy)

you also need to modify some lines where smeshBuilder is used instead of smesh

algo=smesh.xxxx  ==> algo=smeshBuilder.xxxx 

See also SMESH User's Guide for more details

WARNING:
The smesh.py module works correctly only in the first created study.
It does not work in the second, third, etc studies!
