	  to allow parallel execution.
	* [Peter Schiffer]: Fix wrong permissions for data file created

	* NLS updated.

2013/06/09: Version 10.1.6 - Sebastien Godard (sysstat <at> orange.fr)

	* DTD and XSD documents updated. 
	* Code cleaned: Removed several unused constants from header files.

	  not followed by an argument. So it's now possible for example
	  to enter 'iostat -px 2 5' since no device name is given to
	  option -p. This also concerns pidstat option -U.
	* Fixed type for "memfree" and "intr" elements in XSD document.
	* Removed functions used to count number of items from rd_stats.c
	  and put them in a separate file (count.c).

	* pidstat: -U option added. This option tells pidstat to display
	  the username of the task instead of its UID. When this option is
	  followed by a user name, then only tasks belonging to the
	  specified user are displayed by pidstat.
	* pidstat manual page updated.
	* Now use sigaction() instead of signal() for signals handling
	  to avoid portability problems.

          WARNING: This breaks compatibility with older sar data
          files format for IPv6 statistics.
	* [Peter Schiffer]: Added option -y to iostat. This option
	  prevents iostat from displaying its first report with
	  statistics since system boot.
	* [Peter Schiffer]: Increase NR_CPUS and NR_IRQS values.
	* [John Lau]: sadc didn't collect all its activities when
	  it had to overwrite an old sysstat data file with some
	  unknown activity formats. This is now fixed.
	* Now install sadc in $prefix/lib64 directory on 64 bit machines
	  even if $prefix/lib directory also exists.
	* Fixed DTD document: If computer has run all day without
	  restart, XML output file from sadf -x has no boot elements.
	* Remove heading spaces in softirq names displayed by mpstat
	  for easier reading.
	* Fixed wrong command execution syntax in configure script.
	* Removed several unused definitions in some header files.
	* iostat manual page updated.
	* NLS updated.
	* CREDITS file updated.

	  running a niced guest).
	* New field added to sar -r: kbdirty (amount of memory waiting
	  to get written back to disk).
	* [Peter Schiffer]: systemd support added.
	* [Peter Schiffer]: Sysstat init script updated to make it
	  more conforming to LSB.

	* [Peter Schiffer]: Persistent device names support added to

	  with those from latest kernel (3.5).
	  WARNING: This breaks compatibility with older sar data
	  files format for disk activity.
	* [Peter Schiffer]: sar: Use /sys/dev/block/major:minor links
	  to determine devices real name.
	* Part of 'sadf -H' output was written to stderr instead of
	  stdout. This is now fixed.
	* WARNING: sadf: Option '-T' has been renamed into '-U', and
	  option '-t' has been renamed into '-T'.
	* sadf: New option -t added. This option tells sadf to display
	  the timestamps in the local time of the data file creator

	  and usage messages displayed by sysstat commands.
