Quoting Andrew Bartlett <abartlet at samba.org>:

I'm puzzled by how to read that.  Does that mean I use the "samba"  
program to invoke the upgrade?  After a git pull the previous upgrade  
script is gone;  but the syntax to get the same functionality doesn't  
seem obvious.

/opt/s4/sbin/samba domain samba3upgrade --help

doesn't provide any insight.
