Hi, I'm working with the boost's IOStream library adding 
compression/decompression methods others than zip, gzip and bzip2. I'm 
working too adding support to OLE Compound Documents to the same 
library, I'd like to "extract" a containt OLE Document using boost::io 
stream interface.
The problem is I'm not sure how to "return or extract" more than one 
document or compressed file from a stream. All boost examples 
boost::io::copy() a whole stream to another but not just part of it.
I'll appreciate any help, best regards and thank you for such a helpful library
