And at the same time, that is its weak point for packing a large number of similar 
documents, like the LCL documentation. It only compresses one document at a time, so 
it cannot use the information of previous documents for compressing. So it is nice 
for on disk compression, but less valuable for distribution purposes, see also 
Marco's numbers.
