---------------------- ./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.
