I humbly request you to write stuffs on the ALPS webpage, especially on the "Build ALPS from source" section, in a clearer/nicer way. For linux and alps beginners, it's sometimes difficult to understand what different command lines (e.g., cmake -D Boost_ROOT_DIR:PATH...., cmake -DCMAKE_INSTALL_PREFIX...., etc.) do and how one can really use them. Please elaborate every step so that even beginners don't spend too much time to understand what they are doing.
