+! 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.
+!
+! This example is used in the HDF5 Tutorial.
