containing the source zip file at index <var class="Ar">srcidx</var>.

be used in the zip_source. If <var class="Ar">len</var> is 0 or -1, the rest
of the file, starting from <var class="Ar">start</var>, is used. If
<var class="Ar">start</var> is zero and <var class="Ar">len</var> is -1, the
whole file will be copied without decompressing it.</p>
