+ Such a notice grants a world-wide, royalty-free license,

+ generic paint programs or (for drawings) some widely available

+ <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:

+ <listitem>
+ <para>offer you this license which gives you legal
+ permission to copy, distribute and/or modify the
+ software.</para>
+ </listitem>
+ </orderedlist>
+
+ <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.

+ 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

+ terms, do not apply to those sections when you distribute them
+ as separate works. But when you distribute the same sections

- 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>
- 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.

- These requirements apply to the modified work as a whole. If
