JBinHex is both a library and a command-line tool to decode files in
the Apple Macintosh BinHex 4.0 format.
</FONT></P>
<H2>Current version: 0.5</H2>
<H3>Version history:</H3>
<DL>
<DT>0.5
<DD>First released version
</DL>
<H3>Limitations in this version:</H3>
<MENU>
<LI>This version does not support segmented files such as used
on comp.binaries.mac.* newsgroups
<LI>Documentation is limited
<LI>Command line tool has does not check wether the command line
parameters are completely correct
</MENU>
<H3>Possible future features:</H3>
<UL>
<LI>Encoding of BinHex files
<LI>File-based interface that allows to switch between data and
resource fork at any moment, instead of the predetermined order
that the stream-based interface dictates
</UL>
<H3>Command-line tool</H3>
<P>The class name of the command-line tool is <CODE>org.gjt.convert.binhex.DeBinHex</CODE></P>
<P>It accepts the following command line parameters:</P>
<MENU>
<LI>Either <CODE>-u &lt;url&gt;</CODE> or <CODE>-f &lt;file&gt;</CODE>
to specify the source BinHexed file. If neither of those options
is present, <CODE>DeBinHex</CODE> reads <CODE>stdin</CODE>.
<LI><CODE>-d</CODE> to decode the data fork. It will be put in
the file with the name that came from the BinHex header.
<LI><CODE>-df &lt;filename&gt;</CODE> to decode the data fork
to the named file instead of the name that came from the BinHex
header.
<LI><CODE>-r</CODE> to decode the resource fork. It will be put
in the file with the name that came from the BinHex header, with
the extension &quot;<CODE>.resource</CODE>&quot; appended to
it.
<LI><CODE>-rf &lt;filename&gt;</CODE> to decode the resource
fork to the named file instead of the name that came from the
BinHex header.
<LI>Both <CODE>-d</CODE>/<CODE>-df</CODE> options and <CODE>-r</CODE>/<CODE>-rf</CODE>
may be present at the same time. If none of these options is
present, <CODE>DeBinHex</CODE> will decode the data fork as if
the <CODE>-d</CODE> options was specified.
<LI><CODE>-h</CODE> to only show the header of the BinHex file
on <CODE>stdout</CODE>. The decoding options are ignored.
