V-
X    The basic idea of this function is as follows.  Since the central di-
X    rectory lies at the end of the zipfile and the member files lie at the
X    beginning or middle or wherever, it is not very desirable to simply
X    read a central directory entry, jump to the member and extract it, and
X    then jump back to the central directory.  In the case of a large zipfile
X    this would lead to a whole lot of disk-grinding, especially if each mem-
X    ber file is small.  Instead, we read from the central directory the per-
X    tinent information for a block of files, then go extract/test the whole
X    block.  Thus this routine contains two small(er) loops within a very
X    large outer loop:  the first of the small ones reads a block of files
X    from the central directory; the second extracts or tests each file; and
X    the outer one loops over blocks.  There's some file-pointer positioning
X    stuff in between, but that's about it.  Btw, it's because of this jump-
X    ing around that we can afford to be lenient if an error occurs in one of
X    the member files:  we should still be able to go find the other members,
X    since we know the offset of each from the beginning of the zipfile.
X
X    Begin main loop over blocks of member files.  We know the entire central
X    directory is on this disk:  we would not have any of this information un
