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.]

! The following example code shows how to create groups
|
|
! using absolute and relative names. It creates three groups:
|
|
! the first two groups are created using the file identifier and
|
|
! the group absolute names, and the third group is created using
|
|
! a group identifier and the name relative to the specified group.
