[Cin] Revision Proxy section on Manual

[Igor BEGHETTO]

Andrea_paz, Phyllis,
using the Andrea's PDF I write on it some suggestions. I hope it is 
understandable.
My PDF is a raster image of original PDF by Andrea because I don't have 
the font that it uses.

Thanks!

PS:
I understand your good intentions but could you delete my name from the 
Manual, please? (I am already part of the community)
Thanks!
