Most of PSPP is distributed under the GNU General Public |
Specifically, we want to make sure that you have the right to give |
15 |
License. The General Public License says, in effect, that you may |
away copies of PSPP, that you receive source code or else can get it |
16 |
modify and distribute PSPP as you like, as long as you grant the |
if you want it, that you can change these programs or use pieces of |
17 |
same rights to others. It also states that you must provide source code |
them in new free programs, and that you know you can do these things. |
18 |
when you distribute PSPP, or, if you obtained PSPP |
|
19 |
source code from an anonymous ftp site, give out the name of that site. |
To make sure that everyone has such rights, we have to forbid you to |
20 |
|
deprive anyone else of these rights. For example, if you distribute |
21 |
The General Public License is given in full in the source distribution |
copies of PSPP, you must give the recipients all the rights that you |
22 |
as file @file{COPYING}. In Debian GNU/Linux, this file is also |
have. You must make sure that they, too, receive or can get the |
23 |
available as file @file{/usr/share/common-licenses/GPL-2}. |
source code. And you must tell them their rights. |

To quote the GPL itself: |
Also, for our own protection, we must make certain that everyone finds |
26 |
|
out that there is no warranty for PSPP. If these programs are |
