be conveniently linked with application programs (which use some of those func-
tions and data) to form executables.
The "Library", below, refers to any such software library or work which has been
distributed under these terms. A "work based on the Library" means either the
Library or any derivative work under copyright law: that is to say, a work containing
the Library or a portion of it, either verbatim or with modi
fi
cations and/or trans-
lated straightforwardly into another language. (Hereinafter, translation is included
without limitation in the term "modi
fi
cation".)
"Source code" for a work means the preferred form of the work for making modi-
fi
cations to it. For a library, complete source code means all the source code for
all modules it contains, plus any associated interface de
fi
nition
fi
les, plus the scripts
used to control compilation and installation of the library.
Activities other than copying, distribution and modi
fi
cation are not covered by this
License; they are outside its scope. The act of running a program using the Library
is not restricted, and output from such a program is covered only if its contents
constitute a work based on the Library (independent of the use of the Library in
a tool for writing it). Whether that is true depends on what the Library does and
what the program that uses the Library does.
1. You may copy and distribute verbatim copies of the Library's complete source
code as you receive it, in any medium, provided that you conspicuously and ap-
propriately publish on each copy an appropriate copyright notice and disclaimer
of warranty; keep intact all the notices that refer to this License and to the
absence of any warranty; and distribute a copy of this License along with the
Library.
You may charge a fee for the physical act of transferring a copy, and you may at
your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Library or any portion of it, thus
forming a work based on the Library, and copy and distribute such modi
fi
cations
or work under the terms of Section 1 above, provided that you also meet all of
these conditions:
a) The modi
fi
ed work must itself be a software library.
b) You must cause the
fi
les modi
fi
ed to carry prominent notices stating that you
changed the
fi
les and the date of any change.
c) You must cause the whole of the work to be licensed at no charge to all third
parties under the terms of this License.
d) If a facility in the modi
fi
ed Library refers to a function or a table of data to
be supplied by an application program that uses the facility, other than as an
argument passed when the facility is invoked, then you must make a good faith
effort to ensure that, in the event an application does not supply such function or
table, the facility still operates, and performs whatever part of its purpose remains
meaningful.
(For example, a function in a library to compute square roots has a purpose that
is entirely well-de
fi
ned independent of the application. Therefore, Subsection 2d
requires that any application-supplied function or table used by this function must
be optional: if the application does not supply it, the square root function must
still compute square roots.)
These requirements apply to the modi
fi
ed work as a whole. If identi
fi
able sections
of that work are not derived from the Library, and can be reasonably considered
independent and separate works in themselves, then this License, and its terms, do
not apply to those sections when you distribute them as separate works. But when
you distribute the same sections as part of a whole which is a work based on the
Library, the distribution of the whole must be on the terms of this License, whose
permissions for other licensees extend to the entire whole, and thus to each and
every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest your rights to
work written entirely by you; rather, the intent is to exercise the right to control the
distribution of derivative or collective works based on the Library.
In addition, mere aggregation of another work not based on the Library with the
Library (or with a work based on the Library) on a volume of a storage or distribu-
tion medium does not bring the other work under the scope of this License.
3. You may opt to apply the terms of the ordinary GNU General Public License
instead of this License to a given copy of the Library. To do this, you must alter
all the notices that refer to this License, so that they refer to the ordinary GNU
General Public License, version 2, instead of to this License. (If a newer version
than version 2 of the ordinary GNU General Public License has appeared, then
you can specify that version instead if you wish.) Do not make any other change
in these notices.
Once this change is made in a given copy, it is irreversible for that copy, so the or-
dinary GNU General Public License applies to all subsequent copies and derivative
works made from that copy.
This option is useful when you wish to copy part of the code of the Library into a
program that is not a library.
4. You may copy and distribute the Library (or a portion or derivative of it, under
Section 2) in object code or executable form under the terms of Sections 1
and 2 above provided that you accompany it with the complete corresponding
machine-readable source code, which must be distributed under the terms of
Sections 1 and 2 above on a medium customarily used for software interchange.
If distribution of object code is made by offering access to copy from a designated
place, then offering equivalent access to copy the source code from the same place
satis
fi
es the requirement to distribute the source code, even though third parties
are not compelled to copy the source along with the object code.
5. A program that contains no derivative of any portion of the Library, but is
designed to work with the Library by being compiled or linked with it, is called a
"work that uses the Library". Such a work, in isolation, is not a derivative work of
the Library, and therefore falls outside the scope of this License.
However, linking a "work that uses the Library" with the Library creates an execut-
able that is a derivative of the Library (because it contains portions of the Library),
rather than a "work that uses the library". The executable is therefore covered by
this License. Section 6 states terms for distribution of such executables.
When a "work that uses the Library" uses material from a header
fi
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
fi
-
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
fi
ned by law.
If such an object
fi
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
fi
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
fi
cation of the work for the customer's own use and
reverse engineering for debugging such modi
fi
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
fi
ed executable containing
the modi
fi
ed Library. (It is understood that the user who changes the contents
of de
fi
nitions
fi
les in the Library will not necessarily be able to recompile the
application to use the modi
fi
ed de
fi
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
fi
ed version of the library, if
the user installs one, as long as the modi
fi
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
fi
ed in Subsection 6a, above, for a charge no
more than the cost of performing this distribution.
d) If distribution of the work is made by offering access to copy from a desig-
nated place, offer equivalent access to copy the above speci
fi
ed materials from
the same place.
e) Verify that the user has already received a copy of these materials or that you
have already sent this user a copy.
For an executable, the required form of the "work that uses the Library" must
include any data and utility programs needed for reproducing the executable from
it. However, as a special exception, the materials to be distributed need not include
anything that is normally distributed (in either source or binary form) with the
major components (compiler, kernel, and so on) of the operating system on which
the executable runs, unless that component itself accompanies the executable.
It may happen that this requirement contradicts the license restrictions of other
proprietary libraries that do not normally accompany the operating system. Such
a contradiction means you cannot use both them and the Library together in an
executable that you distribute.
7. You may place library facilities that are a work based on the Library side-by-side
in a single library together with other library facilities not covered by this License,
and distribute such a combined library, provided that the separate distribution
of the work based on the Library and of the other library facilities is otherwise
permitted, and provided that you do these two things:
a) Accompany the combined library with a copy of the same work based on
the Library, uncombined with any other library facilities. This must be distributed
under the terms of the Sections above.
b) Give prominent notice with the combined library of the fact that part of it
is a work based on the Library, and explaining where to
fi
nd the accompanying
uncombined form of the same work.
8. You may not copy, modify, sublicense, link with, or distribute the Library except
as expressly provided under this License. Any attempt otherwise to copy, modify,
sublicense, link with, or distribute the Library is void, and will automatically termi-
nate your rights under this License. However, parties who have received copies,
or rights, from you under this License will not have their licenses terminated so
long as such parties remain in full compliance.
9. You are not required to accept this License, since you have not signed it. How-
ever, nothing else grants you permission to modify or distribute the Library or its
derivative works. These actions are prohibited by law if you do not accept this
License. Therefore, by modifying or distributing the Library (or any work based
on the Library), you indicate your acceptance of this License to do so, and all its
terms and conditions for copying, distributing or modifying the Library or works
based on it.
10. Each time you redistribute the Library (or any work based on the Library),
the recipient automatically receives a license from the original licensor to copy,
distribute, link with or modify the Library subject to these terms and condi-
tions. You may not impose any further restrictions on the recipients' exercise
of the rights granted herein. You are not responsible for enforcing compliance
by third parties with this License.
11. If, as a consequence of a court judgment or allegation of patent infringement
or for any other reason (not limited to patent issues), conditions are imposed
on you (whether by court order, agreement or otherwise) that contradict the
conditions of this License, they do not excuse you from the conditions of this
License. If you cannot distribute so as to satisfy simultaneously your obligations
