./html/Datatypes.html
./src/H5T.c
./src/H5Tconv.c
./src/H5Tpkg.h
./src/H5Tpublic.h
./src/H5detect.c
./test/cmpd_dset.c
./test/dsets.c
./test/dtypes.c
./test/external.c
./test/tattr.c
./test/th5s.c
	Organized the predefined data types.

./html/H5.intro.html
	NO MODIFICATIONS!  This file is a mess (obviously generated
	from something else) so I skipped updating it!

./src/h5ls.c
./test/dsets.c
./test/tattr.c
./test/th5s.c
	Added extra argument to H5Sget_dims() calls per Albert's last
	update.
