+CUPS(tm) is provided under the GNU General Public License ("GPL")
+and GNU Library General Public License ("LGPL"), Version 2, with
+exceptions for Apple operating systems and the OpenSSL toolkit. A
+copy of the exceptions and licenses follow this introduction.
-The GNU LGPL applies to the CUPS API library, located in the "cups"
-subdirectory of the CUPS source distribution and in the
-"/usr/include/cups" directory and "libcups.a", "libcups_s.a",
-"libcups.sl", "libcups.so", or "libcups.dylib" files in the binary
-distributions.
+The GNU LGPL applies to the CUPS and CUPS Imaging libraries
+located in the "cups" and "filter" subdirectories of the CUPS
+source distribution and the files in the "test" subdirectory. The
+GNU GPL applies to the remainder of the CUPS distribution.
-The GNU GPL applies to the remainder of the CUPS distribution,
-including the "pstoraster" filter which is based upon GNU Ghostscript
-5.50 and the "pdftops" filter which is based upon Xpdf 0.93a.

+For those not familiar with the GNU GPL, the license basically
+allows you to:
- Use the CUPS software at no charge.
- - Distribute verbatim copies of the software in source or binary
- form.
- - Sell verbatim copies of the software for a media fee, or sell
- support for the software.
- - Distribute or sell printer drivers and filters that use CUPS so
- long as source code is made available under the GPL.
-
-What this license *does not* allow you to do is make changes or add
-features to CUPS and then sell a binary distribution without source
-code. You must provide source for any new drivers, changes, or
-additions to the software, and all code must be provided under the GPL
-or LGPL as appropriate. The only exceptions to this are the portions of
-the CUPS software covered by the Apple operating system license
-exceptions outlined later in this license agreement.
-
-The GNU LGPL relaxes the "link-to" restriction, allowing you to develop
-applications that use the CUPS API library under other licenses and/or
-conditions as appropriate for your application.

-
-APPLE OPERATING SYSTEM DEVELOPMENT LICENSE EXCEPTION
-
-In addition, as the copyright holder of CUPS, Easy Software Products
-grants the following special exception:
-
- Software that is developed by any person or entity for an Apple
- Operating System ("Apple OS-Developed Software"), including but not
- limited to Apple and third party printer drivers, filters, and
- backends for an Apple Operating System, that is linked to the CUPS
- imaging library or based on any sample filters or backends provided
- with CUPS shall not be considered to be a derivative work or
- collective work based on the CUPS program and is exempt from the
- mandatory source code release clauses of the GNU GPL. You may
- therefore distribute linked combinations of the CUPS imaging
- library with Apple OS-Developed Software without releasing the
- source code of the Apple OS-Developed Software. You may also use
- sample filters and backends provided with CUPS to develop Apple
- OS-Developed Software without releasing the source code of the
- Apple OS-Developed Software.
-
-An Apple Operating System means any operating system software developed
-and/or marketed by Apple Computer, Inc., including but not limited to
-all existing releases and versions of Apple's Darwin, Mac OS X, and Mac
-OS X Server products and all follow-on releases and future versions
-thereof.
-
-This exception is only available for Apple OS-Developed Software and
-does not apply to software that is distributed for use on other
-operating systems.
-
-All CUPS software that falls under this license exception have the
-following text at the top of each source file:
-
- This file is subject to the Apple OS-Developed Software exception.

-OPENSSL TOOLKIT LICENSE EXCEPTION
+ - Distribute verbatim copies of the software in source or

+
+LICENSE EXCEPTIONS
+
+In addition, as the copyright holder of CUPS, Apple Inc. grants

+ for an Apple Operating System, that is linked to the
+ CUPS imaging library or based on any sample filters
+ or backends provided with CUPS shall not be
+ considered to be a derivative work or collective work
+ based on the CUPS program and is exempt from the
+ mandatory source code release clauses of the GNU GPL.
+ You may therefore distribute linked combinations of

+
+ 2. OpenSSL Toolkit License Exception;

+
+Sources files containing KSC have the following text at the top
+of each source file:
+
+ This file contains Kerberos support code, copyright 2006 by
+ Jelmer Vernooij.
+
+The KSC copyright and license apply only to Kerberos-related
+feature code in CUPS. Such code is typically conditionally
+compiled based on the present of the HAVE_GSSAPI preprocessor
+definition.
+
+Permission is granted to anyone to use the KSC for any purpose,
+including commercial applications, and to alter it and
+redistribute it freely, subject to the following restrictions:

+ product documentation would be appreciated but is not
+ required.
+
+ 2. Altered source versions must be plainly marked as such,
+ and must not be misrepresented as being the original
+ software.

END OF TERMS AND CONDITIONS

+ Appendix: How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ 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
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) 19yy <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program; if not, write to the Free Software
+ Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) 19yy name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `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 your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.

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