Open Source Software Notice
When a "work that uses the Library" uses material from a header 󳝌le that is part of the Library,
the object code for the work may be a derivative work of the Library even though the source
code is not. Whether this is true is especially signi󳝌cant if the work can be linked without the
Library, or if the work is itself a library. The threshold for this to be true is not precisely de󳝌ned
by law.
If such an object 󳝌le uses only numerical parameters, data structure layouts and accessors, and
small macros and small inline functions (ten lines or less in length), then the use of the object
󳝌le is unrestricted, regardless of whether it is legally a derivative work. (Executables containing
this object code plus portions of the Library will still fall under Section 6.)
Otherwise, if the work is a derivative of the Library, you may distribute the object code for the
work under the terms of Section 6. Any executables containing that work also fall under Section
6, whether or not they are linked directly with the Library itself.
6. As an exception to the Sections above, you may also combine or link a "work that uses the
Library" with the Library to produce a work containing portions of the Library, and distribute that
work under terms of your choice, provided that the terms permit modi󳝌cation of the work for
the customer's own use and reverse engineering for debugging such modi󳝌cations.
You must give prominent notice with each copy of the work that the Library is used in it and that
the Library and its use are covered by this License. You must 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 source
code, so that the user can modify the Library and then relink to produce a modi󳝌ed executable
containing the modi󳝌ed Library. (It is understood that the user who changes the contents of
de󳝌nitions 󳝌les in the Library will not necessarily be able to recompile the application to use the
modi󳝌ed de󳝌nitions.)
b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism
is one that (1) uses at run time a copy of the library already present on the user's computer
system, rather than copying library functions into the executable, and (2) will operate properly
with a modi󳝌ed version of the library, if the user installs one, as long as the modi󳝌ed version is
interface-compatible with the version that the work was made with.
c) Accompany the work with a written offer, valid for at least three years, to give the same
user the materials speci󳝌ed in Subsection 6a, above, for a charge no more than the cost of
