     This module enables you to transparently read ZIP compressed
     archives and the files inside them.

     This module uses the functions of the <ulink
     url="&url.zziplib;">ZZIPlib</ulink> library by Guido Draheim.
     You need ZZIPlib version &gt;= 0.10.6.
    </para>
    <para>
     Note that ZZIPlib only provides a subset of functions
     provided in a full implementation of the ZIP compression algorithm
     and can only read ZIP file archives. A normal ZIP utility is
     needed to create the ZIP file archives read by this library.

     Zip support in PHP is not enabled by default. You will need to
     use the <link linkend="install.configure.with-zip">--with-zip</link>
     configuration option when compiling PHP to enable zip support.
    </para>
    <note>
     <para>
      Zip support before PHP 4.1.0 is experimental.  This section
      reflects the Zip extension as it exists in PHP 4.1.0 and later.

     This example opens a ZIP file archive, reads each file in the
     archive and prints out its contents. The
     <filename>test2.zip</filename> archive used in this example is
     one of the test archives in the ZZIPlib source distribution.
