./html/H5.format.html

./test/Makefile.in
	Symbolic links are now supported.  The ./test/links program
	will create a `links.h5' file that demonstrates hard links,
	soft links, dangling links, and recursive links.  A symbolic
	link is a symbol table entity and doesn't have an object
	header.  It's format is described in H5.format.hml.

./src/H5G.c
./src/H5Gpublic.h
./src/h5ls.c
	Implemented H5Gstat() and H5Gget_linkval() as documented by
	Quincey.  The `H5G_type_t type' field of `H5G_stat_t' was
	changed to `int type' because H5G_type_t was already used and
	the `type' data type should be open-ended.

./src/H5Ffamily.c
	Removed an incorrect diagnostic message.

./test/big.c
	Added read/write calls to test partial I/O to big contiguous
	datasets.  With no arguments it writes to a dataset and prints
	the list of points written which should be redirected to a
	file.  With an argument (the name of a file containing the
	stdout of a run with no arguments) values are read from the
	dataset.  One would typically say `big >x && big x'.
