+! This program creates two files, copy1.h5, and copy2.h5.
+! In copy1.h5, it creates a 3x4 dataset called 'Copy1',
+! and write 0's to this dataset.
+! In copy2.h5, it create a 3x4 dataset called 'Copy2',
+! and write 1's to this dataset.
+! It closes both files, reopens both files, selects two
+! points in copy1.h5 and writes values to them. Then it
+! uses an H5Scopy to write the same selection to copy2.h5.
+! Program reopens the files, and reads and prints the contents of
+! the two datasets.
