APPENDIX > About third party software programs
programs to change the free libraries that are incorporated in them. (We have not seen how to achieve this as
regards changes in header files, but we have achieved it as regards changes in the actual functions of the
Library.) The hope is that this will lead to faster development of free libraries.
The precise terms and conditions for copying, distribution and modification follow. Pay close attention to
the difference between a "work based on the library" and a "work that uses the library". The former contains
code derived from the library, while the latter only works together with the library.
Note that it is possible for a library to be covered by the ordinary General Public License rather than by this
special one.
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any software library which contains a notice placed by the copyright
holder or other authorized party saying it may be distributed under the terms of this Library General Public
License (also called "this License"). Each licensee is addressed as "you".
A "library" means a collection of software functions and/or data prepared so as to be conveniently linked
with application programs (which use some of those functions 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 modifications and/or
translated straightforwardly into another language. (Hereinafter, translation is included without limitation in
the term "modification".)
"Source code" for a work means the preferred form of the work for making modifications to it. For a library,
complete source code means all the source code for all modules it contains, plus any associated interface
definition files, plus the scripts used to control compilation and installation of the library.
Activities other than copying, distribution and modification 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 appropriately 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 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.
