-      facility in <productname>Solaris</productname> 10,

-    </para>

-

-    <para>

-      The provider was integrated into the X.Org git master repository

-      with Solaris 10 &amp; OpenSolaris support for the Xserver 1.4 release,

-      released in 2007 with X11R7.3.   Support for DTrace on MacOS X

-      was added in Xserver 1.7.

-    <para>

-      These probes expose the request and reply structure of the X protocol

-      between clients and the X server, so an understanding of that basic

-      nature will aid in learning how to use these probes.

+      The provider was integrated into the X.Org git master repository
