        + "cannot distribute so as to satisfy simultaneously your obligations under this License "
        + "and any other pertinent obligations, then as a consequence you may not distribute the "
        + "Library at all. For example, if a patent license would not permit royalty-free "
        + "redistribution of the Library by all those who receive copies directly or indirectly "
        + "through you, then the only way you could satisfy both it and this License would be to "

        + "which is implemented by public license practices. Many people have made generous "
        + "contributions to the wide range of software distributed through that system in "
        + "reliance on consistent application of that system; it is up to the author/donor to "

        + "places the Library under this License may add an explicit geographical distribution "
        + "limitation excluding those countries, so that distribution is permitted only in or "
