The licenses for most software are designed to take away your freedom
|
| 26 |
to share and change it. By contrast, the gnu General Public License
|
| 27 |
is intended to guarantee your freedom to share and change free
|
| 28 |
software — to make sure the software is free for all its users. This
|
| 29 |
General Public License applies to most of the Free Software
|
| 30 |
Foundation's software and to any other program whose authors commit
|
| 31 |
to using it. (Some other Free Software Foundation software is covered
|
| 32 |
by the gnu Library General Public License instead.) You can apply it
|
| 33 |
to your programs, too.

When we speak of free software, we are referring to freedom, not
|
| 38 |
price. Our General Public Licenses are designed to make sure that you
|
| 39 |
have the freedom to distribute copies of free software (and charge
|
| 40 |
for this service if you wish), that you receive source code or can
|
| 41 |
get it if you want it, that you can change the software or use pieces
|
| 42 |
of it in new free programs; and that you know you can do these
|
| 43 |
things.
|
| 44 |
|
| 45 |
</para><para>
|
| 46 |
|
| 47 |
To protect your rights, we need to make restrictions that forbid
|
| 48 |
anyone to deny you these rights or to ask you to surrender the
|
| 49 |
rights. These restrictions translate to certain responsibilities for
|
| 50 |
you if you distribute copies of the software, or if you modify it.
|
| 51 |
|
| 52 |
</para><para>
|
| 53 |
|
| 54 |
For example, if you distribute copies of such a program, whether
|
| 55 |
gratis or for a fee, you must give the recipients all the rights that
|
| 56 |
you have. You must make sure that they, too, receive or can get the
|
| 57 |
source code. And you must show them these terms so they know their
|
| 58 |
rights.
|
| 59 |
|
| 60 |
</para><para>
|
| 61 |
|
| 62 |
We protect your rights with two steps: (1) copyright the software,
|
| 63 |
and (2) offer you this license which gives you legal permission to
|
| 64 |
copy, distribute and/or modify the software.
|
| 65 |
|
| 66 |
</para><para>
|
| 67 |
|
| 68 |
Also, for each author's protection and ours, we want to make certain
|
| 69 |
that everyone understands that there is no warranty for this free
|
| 70 |
software. If the software is modified by someone else and passed on,
|
| 71 |
we want its recipients to know that what they have is not the
|
| 72 |
original, so that any problems introduced by others will not reflect
|
| 73 |
on the original authors' reputations.

Finally, any free program is threatened constantly by software
|
| 78 |
patents. We wish to avoid the danger that redistributors of a free
|
| 79 |
program will individually obtain patent licenses, in effect making
|
| 80 |
the program proprietary. To prevent this, we have made it clear that
|
| 81 |
any patent must be licensed for everyone's free use or not licensed
|
| 82 |
at all.

This License applies to any program or other work which contains a
|
| 102 |
notice placed by the copyright holder saying it may be distributed
|
| 103 |
under the terms of this General Public License. The "Program", below,
|
| 104 |
refers to any such program or work, and a "work based on the Program"
|
| 105 |
means either the Program or any derivative work under copyright law:
|
| 106 |
that is to say, a work containing the Program or a portion of it,
|
| 107 |
either verbatim or with modifications and/or translated into another
|
| 108 |
language. (Hereinafter, translation is included without limitation in
|
| 109 |
the term "modification".) Each licensee is addressed as "you".

Activities other than copying, distribution and modification are not
|
| 114 |
covered by this License; they are outside its scope. The act of
|
| 115 |
running the Program is not restricted, and the output from the
|
| 116 |
Program is covered only if its contents constitute a work based on
|
| 117 |
the Program (independent of having been made by running the Program).
|
| 118 |
Whether that is true depends on what the Program does.

You may copy and distribute verbatim copies of the Program's

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

You may modify your copy or copies of the Program or any portion
|
| 141 |
of it, thus forming a work based on the Program, and copy and
|
| 142 |
distribute such modifications or work under the terms of Section 1

|

</para><para>

a) You must cause the modified files to carry prominent notices

|

|
| 150 |
</para><para>

b) You must cause any work that you distribute or publish, that in
|
| 153 |
whole or in part contains or is derived from the Program or any part
|
| 154 |
thereof, to be licensed as a whole at no charge to all third parties
|
| 155 |
under the terms of this License.
|
| 156 |
|
| 157 |
</para><para>
|
| 158 |
|
| 159 |
c) If the modified program normally reads commands interactively when
|
| 160 |
run, you must cause it, when started running for such interactive use
|
| 161 |
in the most ordinary way, to print or display an announcement
|
| 162 |
including an appropriate copyright notice and a notice that there is
|
| 163 |
no warranty (or else, saying that you provide a warranty) and that
|
| 164 |
users may redistribute the program under these conditions, and
|
| 165 |
telling the user how to view a copy of this License. (Exception: if
|
| 166 |
the Program itself is interactive but does not normally print such an
|
| 167 |
announcement, your work based on the Program is not required to print
|
| 168 |
an announcement.)
|
| 169 |
|
| 170 |
</para><para>
|
| 171 |
|
| 172 |
These requirements apply to the modified work as a whole. If
|
| 173 |
identifiable sections of that work are not derived from the Program,
|
| 174 |
and can be reasonably considered independent and separate works in
|
| 175 |
themselves, then this License, and its terms, do not apply to those
|
| 176 |
sections when you distribute them as separate works. But when you
|
| 177 |
distribute the same sections as part of a whole which is a work based
|
| 178 |
on the Program, the distribution of the whole must be on the terms of
|
| 179 |
this License, whose permissions for other licensees extend to the
|
| 180 |
entire whole, and thus to each and every part regardless of who wrote
|
| 181 |
it.

Thus, it is not the intent of this section to claim rights or contest
|
| 186 |
your rights to work written entirely by you; rather, the intent is to
|
| 187 |
exercise the right to control the distribution of derivative or
|
| 188 |
collective works based on the Program.

In addition, mere aggregation of another work not based on the

| 193 |
Program with the Program (or with a work based on the Program) on a
|
| 194 |
volume of a storage or distribution medium does not bring the other
|

work under the scope of this License.

machine-readable copy of the corresponding source code, to be

c) Accompany it with the information you received as to the offer to

distribute corresponding source code. (This alternative is allowed
|

only for noncommercial distribution and only if you received the

The source code for a work means the preferred form of the work for

making modifications to it. For an executable work, complete source

code means all the source code for all modules it contains, plus any
|
| 234 |
associated interface definition files, plus the scripts used to
|
| 235 |
control compilation and installation of the executable. However, as a
|
| 236 |
special exception, the source code distributed need not include
|
| 237 |
anything that is normally distributed (in either source or binary
|
| 238 |
form) with the major components (compiler, kernel, and so on) of the
|

operating system on which the executable runs, unless that component

If distribution of executable or 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 counts as

| 247 |
distribution of the source code, even though third parties are not
|

compelled to copy the source along with the object code.

You may not copy, modify, sublicense, or distribute the Program
|
| 254 |
except as expressly provided under this License. Any attempt
|
| 255 |
otherwise to copy, modify, sublicense or distribute the Program is
|

void, and will automatically terminate your rights under this

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 Program or its derivative works. These actions are
|
| 267 |
prohibited by law if you do not accept this License. Therefore, by
|
| 268 |
modifying or distributing the Program (or any work based on the
|
| 269 |
Program), you indicate your acceptance of this License to do so, and
|
| 270 |
all its terms and conditions for copying, distributing or modifying

Each time you redistribute the Program (or any work based on the

Program), the recipient automatically receives a license from the

original licensor to copy, distribute or modify the Program subject

| 279 |
to these terms and conditions. You may not impose any further
|
| 280 |
restrictions on the recipients' exercise of the rights granted
|
| 281 |
herein. You are not responsible for enforcing compliance by third

If, as a consequence of a court judgment or allegation of patent

infringement or for any other reason (not limited to patent issues),
|
| 289 |
conditions are imposed on you (whether by court order, agreement or
|
| 290 |
otherwise) that contradict the conditions of this License, they do
|
| 291 |
not excuse you from the conditions of this License. If you cannot
|
| 292 |
distribute so as to satisfy simultaneously your obligations under
|
| 293 |
this License and any other pertinent obligations, then as a
|
| 294 |
consequence you may not distribute the Program at all. For example,
|
| 295 |
if a patent license would not permit royalty-free redistribution of
|
| 296 |
the Program by all those who receive copies directly or indirectly
|
| 297 |
through you, then the only way you could satisfy both it and this

License would be to refrain entirely from distribution of the

If you develop a new program, and you want it to be of the greatest
|
| 408 |
possible use to the public, the best way to achieve this is to make
|
| 409 |
it free software which everyone can redistribute and change under
|
| 410 |
these terms.

To do so, attach the following notices to the program. It is safest
|
| 415 |
to attach them to the start of each source file to most effectively
|
| 416 |
convey the exclusion of warranty; and each file should have at least
|
| 417 |
the "copyright" line and a pointer to where the full notice is found.

If the program is interactive, make it output a short notice like
|
| 457 |
this when it starts in an interactive mode:

The hypothetical commands `show w' and `show c' should show the

appropriate parts of the General Public License. Of course, the
|
| 477 |
commands you use may be called something other than `show w' and
|
| 478 |
`show c'; they could even be mouse-clicks or menu items — whatever

suits your program.

You should also get your employer (if you work as a programmer) or
|
| 484 |
your school, if any, to sign a "copyright disclaimer" for the
|
| 485 |
program, if necessary. Here is a sample; alter the names:

This General Public License does not permit incorporating your
|
| 504 |
program into proprietary programs. If your program is a subroutine
|
| 505 |
library, you may consider it more useful to permit linking
|
| 506 |
proprietary applications with the library. If this is what you want
|
| 507 |
to do, use the gnu Library General Public License instead of this
|
| 508 |
License.
