+     There is an optional N argument to this directive that determines 
+     the number of directory levels your session files will be spread
+     around in.  For example, setting to <literal>'5;/tmp'</literal>
+     may end up creating a session file and location like
+     <literal>/tmp/4/b/1/e/3/sess_4b1e384ad74619bd212e236e52a5a174If
+     </literal>.  In order to use N you must create all of these
+     directories before use.  A small shell script exists in
+     <filename>ext/session</filename> to do this, it's called
+     <filename>mod_files.sh</filename>.  Also note that if N is
+     used and greater than 0 then automatic garbage collection will
+     not be performed, see a copy of &php.ini; for further
+     information.  Also, if you use N, be sure to surround
+     <literal>session.save_path</literal> in  
+     "quotes" because the separator (<literal>;</literal>) is
+     also used for comments in &php.ini;.
