<a name="convert2native"><h2>convert2native</h2></a>
Converts an IEEEIO file to the native byte-ordering so that reading can
occur as efficiently as possible. The <i>-byteswap</i> flag causes the
utility to do the opposite (switch to non-native byte ordering). Please
note that ieeeio does not have any problem reading files of any
byte-order, however, byteswapping does exact a performance penalty on
any system. So converting to native byte order improves performance.<P>
<b>usage</b><br>
<code>convert2native [-byteswap] infile outfile</code>
<DL>
<DT><b>infile</b>
<DD>The file to read for translation
<DT><b>oufile</b>
<DD>The file to write to. It will be truncated before it is written to
so don't attempt to write to the input file.
<DT><b>-byteswap</b>
<DD>Forces byte swapping to the opposite of native byte ordering. The
default is to convert to native byte ordering.
</DL>

<a name="ioconvert"><h2>ioconvert</h2></a>
A more general utility than <b>convert2native</b>; <b>ioconvert</b>
converts a file from source format (IEEEIO or HDF) to any allowable
destination format (currently only IEEEIO or HDF). It can also perform
byteswapping to convert to native or the opposite of native format. The
default is native format. <b>convert2native</b> only exists for people
who want the byte-swapping capability but don't wish to compile the full
HDF libraries.<p>
<b>ioconvert</b> senses the filetype by the extension you use for the filename.
<i>.ieee</i> and <i>.raw</i> are interpreted as IEEEIO files and
<i>.hdf</i> is interpreted as an HDF file.<p>
<b>usage</b><br>
<code>ioconvert [-byteswap] infile{.hdf|.ieee|.raw}
outfile{.hdf|.ieee|.raw}</code>
<DL>
<DT><b>infile</b>
<DD>The file to read for translation
<DT><b>oufile</b>
<DD>The file to write to. It will be truncated before it is written to
so don't attempt to write to the input file.
<DT><b>-byteswap</b>
<DD>Forces byte swapping to the opposite of native byte ordering. The
default is to convert to native byte ordering.
</DL>
<hr>
<a name="ioinfo"><h2>ioinfo</h2></a>
Prints out a variety of diagnostic information about IEEEIO and HDF
datafiles. A variety of flags are used to control the amount and the
type of information printed. By default, only information about the
datasets (rank, dimensions and datatype) as well as the number
of attachments will be printed.<p>
<b>usage</b><br>
<code>ioinfo datafile [-showdata | -hidedata]
[-showanndata | -hideanndata] [-showanninfo | -hideanninfo]
[-showattdata | -hideattdata] [-showattinfo | -hideattinfo]
</code>
<DL>
<DT><b>datafile</b>
<DD>The file you wish to examine
<DT><b>-showdata</b> or <b>-data</b>
<DD>Shows the first 10 elements of each dataset.
<DT><b>-hidedata</b> [<i>default</i>]
<DD>Does not show the data, but shows all information about the
datsets like the datatype and the dimensions etc...
<DT><b>-showannotationinfo</b> or <b>-showanninfo</b>
<DD>Shows information about the length of each annotation
bound to a dataset. Otherwise
only the number of annotations is shown for each dataset.
<DT><b>-hideannotationinfo</b> or <b>-hideanninfo</b> [<i>default</i>]
<DD>Only the number of annotations is shown for each dataset.
<DT><b>-showannotationdata</b> or <b>-showanndata</b>
<DD>Shows the first 10 characters of each annotation.
<DT><b>-hideannotationdata</b> or <b>-hideanndata</b> [<i>default</i>]
<DD>None of the contents of the annotations are printed.
<DT><b>-showattributeinfo</b> or <b>-showattinfo</b>
<DD>Shows information about the name, length and datatype of the
attributes for each attribute attached to a dataset. Otherwise
only the number of attributes is shown for each dataset.
<DT><b>-hideattributeinfo</b> or <b>-hideattinfo</b> [<i>default</i>]
<DD>Only the number of attributes is shown for each dataset.
<DT><b>-showattributedata</b> or <b>-showattdata</b>
<DD>Shows the first 10 elements of data stored in an attribute.
<DT><b>-hideattributedata</b> or <b>-hideattdata</b> [<i>default</i>]
<DD>None of the contents of the attribute is printed (except
information if requested).
