The goal of this 
Programemr's Guide is to define some conventions and
to specify some customs to stadardize 
Tango device servers writing style.
It specify the
 Tango naming conventions
Tango project collaboration is based on 
CVS.
There are 2 main repositories:
	-  cvs.sourceforge.net:/cvsroot/tango-cs for kernel modules.
-  cvs.sourceforge.net:/cvsroot/tango-ds for device servers modules.
In addition each institute has is own repository for specific device servers.
A new device server must be added to the apropriate CVS repository in a
new CVS module
When a stable version has been developped and tested, the module must be
 tagged.
It allows to check out this stable version and to know which version is running.
