----------------------

./src/H5T.c
	Fixed a typo in the registration of the `unsigned char' to
	`unsigned long long' type conversion that caused it to not be
	registered, falling back to software whenever that conversion
	path was taken.

./MANIFEST
./test/Makefile.in
./test/testhdf5.c
./test/testhdf5.h
./test/theap.c		[REMOVED]
./test/lheap.c		[NEW]
./test/tohdr.c		[REMOVED]
./test/ohdr.c		[NEW]
./test/tstab.c		[REMOVED]
./test/stab.c		[NEW]
	Removed the `t' from the front of these names and made each
	test a stand-alone program following the format of most of the
	other tests.

./test/big.c
	Uses libh5test.a but always sets the low-level driver to 1GB
	file family.

	The `#if' near the top to set the data space to 8GB has been
	simplified now that `long_long' is always defined and the
	error message is improved when `long_long' isn't wide enough.

	Cleanup code was added to the error handling.

./test/gheap.c
./test/istore.c
	Uses libh5test.a.  Added error cleanup code.

./test/dtypes.c
./test/h5test.c
	Added 68 new tests that check hardware and software
	conversions between `long long' and `unsigned long long' and
	the other integer types.  The tests only run on machines where
	sizeof(long_long)!=sizeof(long).  We test a total of 180
	different integer conversions, half in hardware and half in
	software.

	Cut down the number of times each test is run from 5 to 1 so
	it doesn't take so long.  If you want to run more times
	there's a constant that can be changed at the top of the file.

./test/extend.c
	Removed unused variable.

./test/h5test.c
./test/h5test.h
./test/external.c
./test/fillval.c
	The h5_cleanup() returns true/false so it can be used in an `if'
	statement to clean up additional files.

./doc/html/Environment.html
	Indented.  Added HDF5_PREFIX and HDF5_DRIVER descriptions.

./src/H5P.c
	Changed the trace type for the second argument from `Iu' to
	`x' since it's an output parameter.

./INSTALL
	Added a warning that the GNU zlib that comes with the latest
	version of HDF4 is too old to use with HDF5 and must be
	renamed so configure doesn't see it when `--enable-hdf4' is
	used.

<h2>1. Environment Variables</h2>
<h2>1. Environment Variables</h2>
The HDF5 library uses UNIX environment variables to control
or adjust certain library features at runtime. The variables and
their defined effects are as follows:
The HDF5 library uses UNIX environment variables to control
or adjust certain library features at runtime. The variables and
their defined effects are as follows:
<dir>
<dl>
<dt><tt>HDF5_DEBUG</tt>
<dd>Defines a list of debugging switches documented in the
<a href="Debugging.html">Debugging</a> section of the
<cite>HDF5 User's Guide</cite>.
<center>
<table width="90%">
<tr>
<th>Variable</th>
<th>Description</th>
</tr>
<dt><tt>HDF5_NOCLEANUP</tt>
<dd>When set to a non-empty value, the programs in the test
directory do not remove temporary HDF5 data files.
The default is for each test to remove the files before exit.
<tr valign=top>
<td><code>HDF5_DEBUG</code></td>
<td>Defines a list of debugging switches documented in the
<a href="Debugging.html">Debugging</a> section of the
<cite>HDF5 User's Guide</cite>.</td>
</tr>
<dt><tt>HDF5_MPI_OPT_TYPES</tt>
&nbsp;&nbsp;(for parallel beta version only)
<dd>When set to <code>1</code>, PHDF5 will use the MPI optimized
code to perform parallel read/write accesses to datasets.
Currently, this optimization fails when accessing extendable
datasets. The default is not to use the optimized code.
<tr valign=top>
<td><code>HDF5_NOCLEANUP</code></td>
<td>If set then programs in the test directories do not
remove temporary files. The default is for each test to
remove the files before exit if the test succeeds but to
leave the files if the test fails.</td>
</tr>
<dt><tt>HDF5_MPI_1_METAWRITE</tt>
&nbsp;&nbsp;(for parallel beta version only)
<dd>When set to <code>1</code>, PHDF5 will write the metadata
via process 0 of each opened parallel HDF5 file. This should
improve I/O throughput. The default is not to use this
optimization.
<tr valign=top>
<td><code>HDF5_PREFIX</code></td>
<td>The value of this variable is prepended to all temporary
file names created by the test programs and separated from
the base name of the file by a slash. The default is no
prefix.</td>
</tr>
</dl>
</dir>
<tr valign=top>
<td><ode>HDF5_DRIVER</code></td>
<td>This variable should hold the name of a low-level HDF5
file driver such as <code>sec2</code>, <code>stdio</code>,
<code>core</code>, <code>split</code>, or
<code>family</code>. The family driver also takes an
optional real-valued family member size in MB which
defaults to 1. If this variable is not set or empty then
the library-defined default file driver is used (which can
be set at configuration time with the H5F_LOW_DFLT cpp
constant, usually <code>sec2</code>).</td>
</tr>
<h2>2. Configuration Parameters</h2>
<tr valign=top>
<td><code>HDF5_MPI_OPT_TYPES</code></td>
<td>When set to <code>1</code>, parallel HDF5 will use the
MPI-optimized code to perform parallel read/write accesses
to datasets. Currently, this optimization fails when
accessing extendable datasets. The default is not to use
the optimized code.</td>
</tr>
The HDF5 configuration script accepts a list of parameters to control
configuration features when creating the Makefiles for the library.
The command
<br>
<code>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;configure --help </code>
<br>
will display the current list of parameters and their effects.
<tr valign=top>
<td><code>HDF5_MPI_1_METAWRITE</code></td>
<td>When set to <code>1</code>, parallel HDF5 will write the
metadata via process 0 of each opened parallel HDF5 file.
This should improve I/O throughput. The default is not to
use this optimization.</td>
