    # Most of the terminals process ANSI-sequences
    # wrongly without that. Also, apparently, this
    # affects `ioctl(STDOUT_FILENO, TIOCGWINSZ, &w)`
    # which can give wrong size (I've observed 80x
    # 300 in some cases, which contradicts the rea-
    # lity).

    #   I recommend  using `iTerm2` or `xterm` and
    # maximize the terminal window under Mac OS X

    export TERM=vt100
#   export TERM=xterm

#else
    # It perfectly works under any Linux terminal
    # No need to prepare anything
