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 compile
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 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) 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.

    c) 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.

    d) 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 source code 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 to 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
people have made generous contributions to the wide range of
software distributed through that system in reliance on
consistent application of that system; it is up to the
author/donor to decide if he or she is willing to distribute
software through any other system and a licensee cannot impose
that choice.

This section is intended to make thoroughly clear what is
believed to be a consequence of the rest of this License.

12. If the distribution and/or use of the Library is restricted
in certain countries either by patents or by copyrighted
interfaces, the original copyright holder who places the Library
under this License may add an explicit geographical distribution
limitation excluding those countries, so that distribution is
permitted only in or among countries not thus excluded.  In such
case, this License incorporates the limitation as if written in
the body of this License.

13. The Free Software Foundation may publish revised and/or new
versions of the Library General Public License from time to
time. Such new versions will be similar in spirit to the present
version, but may differ in detail to address new problems or
concerns.

Each version is given a distinguishing version number.  If the
Library specifies a version number of this License which applies
to it and "any later version", you have the option of following
the terms and conditions either of that version or of any later
version published by the Free Software Foundation.  If the
Library does not specify a license version number, you may
choose any version ever published by the Free Software
Foundation.

14. If you wish to incorporate parts of the Library into other
free programs whose distribution conditions are incompatible
with these, write to the author to ask for permission.  For
software which is copyrighted by the Free Software Foundation,
write to the Free Software Foundation; we sometimes make
exceptions for this.  Our decision will be guided by the two
goals of preserving the free status of all derivatives of our
free software and of promoting the sharing and reuse of software
generally.

                           NO WARRANTY

  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND,
EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL
DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

                    END OF TERMS AND CONDITIONS

 Appendix: How to Apply These Terms to Your New Libraries

If you develop a new library, and you want it to be of the
greatest possible use to the public, we recommend making it free
software that everyone can redistribute and change.  You can do
so by permitting redistribution under these terms (or,
alternatively, under the terms of the ordinary General Public
License).

To apply these terms, attach the following notices to the
library.  It is safest to attach them to the start of each
source file to most effectively convey the exclusion of
warranty; and each file should have at least the "copyright"
line and a pointer to where the full notice is found.

    <one line to give the library's name and a brief idea of what it does.>
    Copyright (C) <year>  <name of author>

    This library is free software; you can redistribute it and/or
    modify it under the terms of the GNU Library General Public
    License as published by the Free Software Foundation; either
    version 2 of the License, or (at your option) any later version.

    This library is distributed in the hope that it will be useful,
    but WITHOUT ANY WARRANTY; without even the implied warranty of
    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
    Library General Public License for more details.

    You should have received a copy of the GNU Library General Public
    License along with this library; if not, write to the Free
    Software Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.

Also add information on how to contact you by electronic and paper mail.

You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the library, if
necessary.  Here is a sample; alter the names:

  Yoyodyne, Inc., hereby disclaims all copyright interest in the
  library `Frob' (a library for tweaking knobs) written by James Random Hacker.

  <signature of Ty Coon>, 1 April 1990
  Ty Coon, President of Vice

That's all there is to it!
