<dt><strong>Purpose:</strong>
<dd>Imports data into an existing or new HDF5 file.
<dt><strong>Description:</strong>
<dd><code>h5import</code> converts data
from one or more ASCII or binary files, <code><i>infile</i></code>,
into the same number of HDF5 datasets
in the existing or new HDF5 file, <code><i>outfile</i></code>.
Data conversion is performed in accordance with the
user-specified type and storage properties
specified in <code><em>in_options</em></code>.
<p>
The primary objective of <code>h5import</code> is to
import floating point or integer data.
The utility's design allows for future versions that
accept ASCII text files and store the contents as a
compact array of one-dimensional strings,
but that capability is not implemented in HDF5 Release 1.6.
<p>
<b>Input data and options:</b><br>
Input data can be provided in one of the follwing forms:
<ul><li>As an ASCII, or plain-text, file containing either
floating point or integer data
<li>As a binary file containing either 32-bit or
64-bit native floating point data
<li>As a binary file containing native integer data,
signed or unsigned and
8-bit, 16-bit, 32-bit, or 64-bit.
<li>As an ASCII, or plain-text, file containing text data.
(This feature is not implemented in HDF5 Release 1.6.)
</ul>
Each input file, <code><i>infile</i></code>,
contains a single <em>n</em>-dimensional
array of values of one of the above types expressed
in the order of fastest-changing dimensions first.
<p>
Floating point data in an ASCII input file must be
expressed in the fixed floating form (e.g., 323.56)
<code>h5import</code> is designed to accept scientific notation
(e.g., 3.23E+02) in an ASCII, but that is not implemented in HDF5 release 1.6.
<p>
Each input file can be associated with options specifying
the datatype and storage properties.
These options can be specified either as
<em>command line arguments</em>
or in a <em>configuration file</em>.
Note that exactly one of these approaches must be used with a
single input file.
<p>
Command line arguments, best used with simple input files,
can be used to specify
the class, size, dimensions of the input data and
a path identifying the output dataset.
<p>
The recommended means of specifying input data options
is in a configuration file; this is also the only means of
specifying advanced storage features.
See further discussion in "The configuration file" below.
<p>
The only required option for input data is dimension sizes;
defaults are available for all others.
<p>
<code>h5import</code> will accept up to 30 input files in a single call.
Other considerations, such as the maximum length of a command line,
may impose a more stringent limitation.
<p>
<b>Output data and options:</b><br>
The name of the output file is specified following
the <code>-o</code> or <code>-output</code> option
in <code><i>outfile</i></code>.
The data from each input file is stored as a separate dataset
in this output file.
<code><i>outfile</i></code> may be an existing file.
If it does not yet exist, <code>h5import</code> will create it.
<p>
Output dataset information and storage properties can be
specified only by means of a configuration file.

<b>Command-line arguments:</b><br>
The <code>h5import</code> syntax for the command-line arguments,
<code><em>in_options</em></code>, is as follows:
<table width=100% border=0>
<tr><td>&nbsp;&nbsp;&nbsp;&nbsp;</td><td>
<code>h5import <em>infile</em> -d <em>dim_list</em>
[-p <em>pathname</em>]
[-t <em>input_class</em>]
[-s <em>input_size</em>]
[<em>infile</em> ...]
-o <em>outfile</em></code><br>
or<br>
<code>h5import <em>infile</em> -dims <em>dim_list</em>
[-path <em>pathname</em>]
[-type <em>input_class</em>]
[-size <em>input_size</em>]
[<em>infile</em> ...]
-outfile <em>outfile</em></code><br>
or<br>
<code>h5import <em>infile</em> -c <em>config_file</em>
[<em>infile</em> ...]
-outfile <em>outfile</em></code>
</td></tr>
</table>
Note the following:
If the <code>-c <em>config_file</em></code> option is used with
an input file, no other argument can be used with that input file.
If the <code>-c <em>config_file</em></code> option is not used with
an input data file, the <code>-d <em>dim_list</em></code> argument
(or <code>-dims <em>dim_list</em></code>)
must be used and any combination of the remaining options may be used.
Any arguments used must appear in <em>exactly</em> the order used
in the syntax declarations immediately above.
<p>
<b>The configuration file:</b><br>
A configuration file is specified with the
<code>-c <em>config_file</em></code> option:
<table border=0>
<tr><td>&nbsp;&nbsp;&nbsp;&nbsp;</td><td>
<code>h5import <em>infile</em> -c <em>config_file</em>
[<em>infile</em> -c <em>config_file2</em> ...]
-outfile ><em>outfile</em></code>
</td></tr>
</table>
<p>
The configuration file is an ASCII file and must be
organized as "Configuration_Keyword Value" pairs,
with one pair on each line.
For example, the line indicating that
the input data class (configuration keyword <code>INPUT-CLASS</code>)
is floating point in a text file (value <code>TEXTFP</code>)
would appear as follows:<br>
<code>&nbsp;&nbsp;&nbsp;&nbsp;INPUT-CLASS&nbsp;TEXTFP</code>
<p>
A configuration file may have the following keywords each
followed by one of the following defined values.
One entry for each of the first two keywords,
<code>RANK</code> and <code>DIMENSION-SIZES</code>,
is required; all other keywords are optional.
