supply a copy of this License. If the work during execution displays copyright notices,
you must include the copyright notice for the Library among them, as well as a reference
directing the user to the copy of this License. Also, you must do one of these things: 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
