- Add CGAL_DONT_HAVE_MEMORY_SIZER to detect on which platforms it works,
  and make the test-suite emit a warning instead of an error in this case.

26 March 2004 Radu Ursu
- made doc work with the current implementation of the Manual tools

2.12 (12 Jan 2004)
- Add Memory_sizer

============================ CGAL 3.0 ============================

2.11 (22 Oct 2003)
- new headers

2.10 (22 Sep 2003)
- new headers

2.9 (10 Jan 2003)

     - Added Metrowerks support (patch by Radu Ursu).

2.7 (29 Apr 2002)
     - split of user and reference manuals

2.6 (04 Apr 2002)

     - Changed details to get rid of spurious negative (small) timing
       and precision results which I attribute to problems with
       different rounding behavior of double and inline code in different
       places (but just a hunch).

2.5 (25 Mar 2002)

     - Moved #include <float.h> in Timer.C to get always included.

2.4 (21 Mar 2002)

     - Maintenance moved to Lutz Kettner, MPI Saarbruecken.

2.3 (20 Mar 2002)

     - Added missing float.h file to include/CGAL/Real_timer.h.

2.2 (18 Mar 2002)

     - Improved Timer based on getrusage() on POSIX systems (does
       not wrap around after 30 minutes).
     - Error behaviour of both timer classes changed to warning
       and proper error return values.
     - Rewritten test program (more modular, since both timers are so similar.
     - Cleanup at some places, all based on one system depending function
       returning a time in seconds in one double.
     - Changed the precision function to compute the precision dynamically
       at runtime at its first invocation.

2.1.1 (10 Dec 2001)

     Real_timer changes from Andreas Fabri for MWCC included

2.1 (28 Sept 2001)

     some consts in Real_timer.h removed (caused KCC warnings)

2.0 (20 June 2001)

     manual split

1.9 (4  April 2001)

     changes in Real_timer.h to avoid warnings

1.8 (11 August 2000)

     change to ccRefName in the manual

1.7 (14 April 2000)

     changed the manual a bit

1.6 (1 Feb 2000)

     some changes for Borland C++
     Real_timer.h reorganized a bit

1.5

     CGAL_CLIB_STD added at a few places

1.4 (20 Sept 1999)

     endl 's removed

1.3 (17 Sept 1999)

     added std:: to cerr

1.2 (13 Sept 1999)

     Changes for Visual C++; uses _ftime on this platform for Real_timer

1.1 (05 Mar 1999)

     Standard headers, std namespace and CGAL namespace.
     This new package is spawned from the old Support_LK package
     1.18 (07 Oct 1998). Timer.h and Real_timer.h are here separated 
     in their own package to reflect that they have their own chapter
     in the manual.
