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 modifications or work under the terms of
Section 1 above, provided that you also meet all of these conditions: a) The modified work must
itself be a software library. b) You must cause the files modified to carry prominent notices
stating that you changed the files 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 modified 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-defined 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 modified work as a whole. If
identifiable 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 distribution 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 ordinary 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
satisfies 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
executable 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 file 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 significant 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 defined by law.If such an object file 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 file 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 modification of the work
for the customer's own use and reverse engineering for debugging such modifications. You
must give prominent notice with each copy of the work that the Library is used in it and that the
30
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 modified executable containing the modified Library. (It is understood that
the user who changes the contents of definitions files in the Library will not necessarily be able
to recompile the application to use the modified definitions.) 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 modified version of the
library, if the user installs one, as long as the modified 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 specified 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 designated place, offer equivalent access to copy the
above specified 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 find 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 terminate 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. However, 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 conditions. 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 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 refrain
entirely from distribution of the Library. If any portion of this section is held invalid or
unenforceable under any particular circumstance, the balance of the section is intended to
apply, and the section as a whole is intended to apply in other circumstances. It is not the
purpose of this section to induce you to infringe any patents or other property right claims or to
contest validity of any such claims; this section has the sole purpose of protecting the integrity of
the free software distribution system which is implemented by public license practices. Many
