    35  * The Pablo compiler translates Pablo code to C++ code as follows.
     35 * The \s2k{} compiler translates \s2k{} to \b2k{} to C++ code as follows.
    3636 *
    37  * 1. \s2k{} stream structures to C/C++ structures, i.e., simple data containers.
     37 * 1. \s2k{} stream structures to \b2k{} bitblock structure
     38 *    to bitblock C/C++ structures, i.e., simple data containers.
    3839 *
    39  * 2. \s2k{} stream functions to C/C++ structures, i.e., objects with methods.
     40 * 2. \s2k{} stream filters to \b2k{} bitblock kernels to
     41 *    C/C++ structures, i.e., objects with methods.
    4042 *    C/C++ structures are generated with `do_block', `do_final_blocks', `clear'
    4143 *    member functions, as well as member variables to capture
