[Wien] electron doping while maintaining the overall neutrality of the system

Dear WIEN2k developers and users,Hi,
I am inquiring about the possibility of describing with WIEN2K a doped 
system by varying the total number of electrons (NE) while keeping the 
system neutral.
In particular I found in the web that the electron number can be 
varied by changing the parameter NE in the file case.in2  and by setting +1 
or -1 in the file  case.inm .
The question is: Does this procedure merely increment the NE leaving the 
system charged because of an unbalanced NE or a corresponding background 
charge is (or can be) introduced to balance the changed NE to leave the 
system neutral?Your help is highly appreciated.With best regardsMohammed
