    directory tree.  In a typical installation, platform dependent files may be
    installed in the /usr/local/plat subtree while platform independent may
    be installed in /usr/local.

    Generally speaking, a platform is a combination of hardware and software
    families, e.g.  Sparc machines running the Solaris 2.x operating system are
    considered the same platform, but Intel machines running Solaris 2.x are another
    platform, and Intel machines running Linux are yet another platform.  Different
    major revisions of the same operating system generally also form different
    platforms.  Non-Unix operating systems are a different story; the installation
    strategies on those systems are so different that the prefix and exec-prefix are
    meaningless, and set to the empty string. Note that compiled Python bytecode
    files are platform independent (but not independent from the Python version by
    which they were compiled!).
