#include <iostream>
#include <sstream>
#include

using namespace std;
int main()

        out.push(boost::iostreams::zlib_compressor());
        out.push(boost::iostreams::back_inserter(compressed));
        boost::iostreams::copy(boost::make_iterator_range(message), out);

        boost::iostreams::copy(in, 
        boost::iostreams::back_inserter(decompressed));
        cout << "decompressed message: " << decompressed << endl;
}
# g++ zlib.cpp zlib_test2.cpp -o zlib_test2 -lz

message: this is a test message!
