OK, I found some...

>From the manual at "MyISAM tables"...

"Internal handling of one AUTO_INCREMENT column. MyISAM will
automatically update this on INSERT/UPDATE. The AUTO_INCREMENT value can
be reset with myisamchk. This will make AUTO_INCREMENT columns faster
(at least 10 %) and old numbers will not be reused as with the old ISAM.
Note that when a AUTO_INCREMENT is defined on the end of a
multi-part-key the old behavior is still present."

 Well...and what about the last phrase "Note that..."? I didn't
understand it.
 Maybe I'm having a bad design problem since I'm using the
auto_increment feature to define the number of the editions of my
bulletins. I'm studying other ways to do it.
