<a name="l00023"></a>00023 <span class="comment"> behaves just as expected (i hope ;-) ).</span>
<a name="l00024"></a>00024 <span class="comment"> It can also be used in IO_ReadWrite mode, in this case one can</span>
<a name="l00025"></a>00025 <span class="comment"> append files to an existing zip archive. when you append new files, which</span>
<a name="l00026"></a>00026 <span class="comment"> are not yet in the zip, it works as expected, they are appended at the end.</span>
<a name="l00027"></a>00027 <span class="comment"> when you append a file, which is already in the file, the reference to the</span>
<a name="l00028"></a>00028 <span class="comment"> old file is dropped and the new one is added to the zip. but the</span>
<a name="l00029"></a>00029 <span class="comment"> old data from the file itself is not deleted, it is still in the</span>
<a name="l00030"></a>00030 <span class="comment"> zipfile. so when you want to have a small and garbagefree zipfile,</span>
<a name="l00031"></a>00031 <span class="comment"> just read the contents of the appended zipfile and write it to a new one</span>
<a name="l00032"></a>00032 <span class="comment"> in IO_WriteOnly mode. especially take care of this, when you don't want</span>
