Hi, all I was playing around with iostreams recently, and I found that some examples of iostreams include the header file: boost/iostreams/stream_facade.hpp But I cannot find this header any where. I noticed that in the 1.34 release, iostreams is entirely outdated, and I waited until 1.34.1, but this mysterious header is still missing. I apologize if the file just stands right there but somehow I managed to miss it. Also, I think there should be a Jamfile to compile and test the examples. The documentation is pretty useful but well organized and offers many code snippet but never a compilable example as a whole. Fortunately the test cases offered many useful use cases :-) Cheers Cheng
