./MANIFEST
./src/H5Dconv.c		[REMOVED]
./src/H5Tconv.c		[NEW]
./src/Makefile.in
	Changed H5Dconv.c to H5Tconv.c

./html/Datatypes.html
	Updated data type conversion section.

./html/H5.apiv2.html
	Removed sections about datasets and data types since they're
	covered in their own chapters.

./src/H5D.c
	Supports data type conversion.

./src/H5Odtype.c
./src/H5Tpkg.h
	Changed `lo_pad' and `hi_pad' to `lsb_pad' and `msb_pad'.

./src/H5T.c
./src/H5Tpkg.h
./src/H5Tprivate.h
./src/H5Tpublic.h
./src/H5detect.c
	Added predefined data types. Added query/set more
	properties. Added type conversion infrastructure.

./test/dsets.c
	Tests data type conversion during read.
