add "cannot skip over prefix" to the list of limitations
<li>may return unknown sizes and CRC values for entries
until the next entry has been reached if the archive uses
the data descriptor feature (see below).</li>
+ <li>can not skip over bytes that occur before the real zip
+ stream. This means self-extracting zips as they are created
+ by some tools can not be read using
+ <code>ZipArchiveInputStream</code> at all. This also applies
+ to Chrome extension archives, for example.</li>
</ul>
<p><code>ZipArchiveInputStream</code> shares these limitations
