<title>Preamble</title>
|
|
<para> The licenses for most software are designed to take away your
|
|
freedom to share and change it. By contrast, the GNU General Public License is
|
|
intended to guarantee your freedom to share and change
|
|
free software - to make sure the software is free for all its users.
|
|
This General Public License applies to most of the Free Software
|
|
Foundation's software and to any other program whose authors commit
|
|
to using it. (Some other Free Software Foundation software is covered
|
|
by the GNU Library General Public License instead.) You can apply it
|
|
to your programs, too.
|
|
</para>
|
|
<para> When we speak of free software, we are referring to freedom, not price.
|
|
Our General Public Licenses are designed to make sure that you have the
|
|
freedom to distribute copies of free software (and charge for this
|
|
service if you wish), that you receive source code or can get it if you
|
|
want it, that you can change the software or use pieces of it in new free
|
|
programs; and that you know you can do these things.
|
|
</para>
|
|
<para> To protect your rights, we need to make restrictions that forbid anyone
|
|
to deny you these rights or to ask you to surrender the rights. These
|
|
restrictions translate to certain responsibilities for you if you distribute
|
|
copies of the software, or if you modify it.
|
|
</para>
|
|
<para> For example, if you distribute copies of such a program, whether gratis or
|
|
for a fee, you must give the recipients all the rights that you have. You
|
|
must make sure that they, too, receive or can get the source code. And you
|
|
must show them these terms so they know their rights.
|
|
</para>
|
|
<para> We protect your rights with two steps:
|
|
<orderedlist>
|
|
<listitem>
|
|
<para> copyright the software, and
|
|
</para>
|
|

|
|
<para> offer you this license which gives you legal permission to copy,
|
|
distribute and/or modify the software.
|
|
</para>
|
|
</listitem>
|
|
</orderedlist>
|
|
</para>
|
|
<para> Also, for each author's protection and ours, we want to make certain that
|
|
everyone understands that there is no warranty for this free software. If
|
|
the software is modified by someone else and passed on, we want its
|
|
recipients to know that what they have is not the original, so that any
|
|
problems introduced by others will not reflect on the original authors'
|
|
reputations.
|
|
</para>
|
|
<para> Finally, any free program is threatened constantly by software patents.
|
|
We wish to avoid the danger that redistributors of a free program will
|
|
individually obtain patent licenses, in effect making the program
|
|
proprietary. To prevent this, we have made it clear that any patent must be
|
|
licensed for everyone's free use or not licensed at all.

<sect2 id="gpl-2-0">
|
|
<title>Section 0</title>
|
|
<para> This License applies to any program or other work which contains a notice
|
|
placed by the copyright holder saying it may be distributed under the terms
|
|
of this General Public License. The "Program", below, refers to any such
|
|
program or work, and a
|
|
<quote>work based on the Program
|
|
</quote> means either
|
|
the Program or any derivative work under copyright law: that is to say, a
|
|
work containing the Program or a portion of it, either verbatim or with
|
|
modifications and/or translated into another language. (Hereinafter, translation
|
|
is included without limitation in the term
|
|
<quote>modification
|
|
</quote>.) Each licensee is addressed as <quote>you</quote>.
|
|
</para>
|
|
<para> Activities other than copying, distribution and modification are not covered by
|
|
this License; they are outside its scope. The act of running the Program is not
|
|
restricted, and the output from the Program is covered only if its contents
|
|
constitute a work based on the Program (independent of having been made by running
|
|
the Program). Whether that is true depends on what the Program does.

keep intact all the notices that refer to this License and to the absence of any

<para> You must cause any work that you distribute or publish, that in whole or

in part contains or is derived from the Program or any part thereof, to be

|
|
this License.

</para>

</listitem>
|

<listitem>
|

<para> If the modified program normally reads commands interactively when run, you
|
|
must cause it, when started running for such interactive use in the most

ordinary way, to print or display an announcement including an appropriate

copyright notice and a notice that there is no warranty (or else, saying
|
|
that you provide a warranty) and that users may redistribute the program
|
|
under these conditions, and telling the user how to view a copy of this
|
|
License.
|
|
<note>
|
|
<title>Exception:
|
|
</title>
|
|
<para> If the Program itself is interactive but does not normally print such an
|

announcement, your work based on the Program is not required to print an

announcement.)

</listitem>

|

</para>
|
|
<para> These requirements apply to the modified work as a whole. If identifiable sections
|
|
of that work are not derived from the Program, 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
|
|
Program, 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.
|
|
</para>
|
|
<para> 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 Program.
|
|
</para>
|
|
<para> In addition, mere aggregation of another work not based on the Program with the Program
|

(or with a work based on the Program) on a volume of a storage or distribution medium

does not bring the other work under the scope of this License.

If you develop a new program, and you want it to be of the greatest

To do so, attach the following notices to the program. It is safest

to attach them to the start of each source file to most effectively

the "copyright" line and a pointer to where the full notice is found.
