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