[Boost-users] Question regarding using asn1 boost libraries

Dear friends, From the URL "http://www.ibusy.com/devtree/asn1/boost_asn1/linking.html", I learnt that boost has support for ASN1 (Abstract Syntax Notation) encoding and decoding using BER (Basic Encoding Rules). But when I downloaded the boost tar zip file, i could not find the below header file(s): #include <boost/asn1/asn1.hpp> Can someone help me where to get the ASN1 support header files for boost... Thanks and regards, RV
