[svn-r3561] add to tutorial
Purpose: [is this a bug fix? feature? ...] Description: [describe the bug, or describe the new feature, etc] Solution: [details about the changes, algorithm, etc...] [Please as detail as you can since your own explanation is better than others guessing it from the code.] Platforms tested: [machines you have tested the changed version. This is absolute important. Test it out on at least two or three different platforms such as Big-endian-32bit (SUN/IRIX), little-endian-32(LINUX) and 64-bit (IRIX64/UNICOS/DEC-ALPHA) would be good.]
