      For example, if you distribute copies of the library, whether gratis
    or for a fee, you must give the recipients all the rights that we gave
    you.  You must make sure that they, too, receive or can get the source
    code.  If you link other code with the library, you must provide
    complete object files to the recipients, so that they can relink them
    with the library after making changes to the library and recompiling
    it.  And you must show them these terms so they know their rights.

    a) Accompany the work with the complete corresponding
    machine-readable source code for the Library including whatever
    changes were used in the work (which must be distributed under
    Sections 1 and 2 above); and, if the work is an executable linked
    with the Library, with the complete machine-readable "work that
    uses the Library", as object code and/or source code, so that the
    user can modify the Library and then relink to produce a modified
    executable containing the modified Library.
