How about:

 * The maintainers are listed in the MAINTAINERS file at the top of the Xen 
source tree. If no maintainer is listed then there is no need for a CC (if you 
are modifying code with no maintainer then you might like to consider becoming 
the maintainer for that piece of code!).
 ** You can pipe your patch to the <code>./scripts/get_maintainer.pl</code> 
tool and it will list the relevant maintainers.
 * In addition to CCing the maintainer you should always send patches to (via 
TO) the xen-devel@xxxxxxxxxxxxxxxxxxxx mailing list as well.
-* To add a CC when sending the mail you can use the ''--cc'' option to the 
''git send-email'' command, or you can do it manually in your MUA.
+* To add a CC when sending the mail you can:

+or:
+<pre>
+git send-email --cc-cmd="scripts/get_maintainer.pl

+which will automatically add the proper maintainer on the CC line.
+The ''no-l'' is to not add the mailing list to the CC (as you would

+  * or you can do it manually in your MUA.

+In short, it could look like this:
+<pre>
+$pwd
+/home/joe/xen
+git send-email --cc-cmd="scripts/get_maintainer.pl --no-l --to 
xen-devel@xxxxxxxxxxxxxxxxxxxx --to jo@xxxxxxxxxxx --compose --subject "[PATCH 
v1] Fixes to frobnicator." *.patch
+</pre>
+
+Which will send all patches to yourself on the TO, to xen-devel mailiing list 
(on the TO:)
+and the patches will have their CC: list generated based on 
scripts/get_maintainer.pl.
