</PRE>

Reimplementation of <CODE>java.util.zip.ZipOutputStream</CODE> that does handle the extended
 functionality of this package, especially internal/external file
 attributes and extra fields with different layouts for local file
 data and central directory entries.

This class will try to use <CODE>RandomAccessFile</CODE> when you know that the output is going to go to a
 file.

If RandomAccessFile cannot be used, this implementation will use
 a Data Descriptor to store size and CRC information for <A HREF="../../../../org/apache/tools/zip/ZipOutputStream.html#DEFLATED"><CODE>DEFLATED</CODE></A> entries, this means, you don't need to
 calculate them yourself. Unfortunately this is not possible for
 the <A HREF="../../../../org/apache/tools/zip/ZipOutputStream.html#STORED"><CODE>STORED</CODE></A> method, here setting the CRC and
 uncompressed size information is required before <A HREF="../../../../org/apache/tools/zip/ZipOutputStream.html#putNextEntry(org.apache.tools.zip.ZipEntry)"><CODE>putNextEntry</CODE></A> can be called.
