            INTRODUCTION
            
            The Common UNIX Printing System(tm), ("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
            "cups" include directory and library files in the binary
            distributions. The GNU GPL applies to the remainder of the CUPS
            distribution, including the "pdftops" filter which is based upon
            Xpdf and the CUPS imaging library.
            
            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.
            
            
            LICENSE EXCEPTIONS
            
            In addition, as the copyright holder of CUPS, Easy Software
            Products grants the following special exceptions:
            
                 1. Apple Operating System Development License Exception;
            
            	a. 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.
            
            	b. 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.
            
            	c. 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.
            
            	d. 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.
            
                 2. OpenSSL Toolkit License Exception;
            
            	a. Easy Software Products explicitly allows the
            	   compilation and distribution of the CUPS software
            	   with the OpenSSL Toolkit.
            
            No developer is required to provide these exceptions in a
            derived work.
            
            
            TRADEMARKS
            
            Easy Software Products has trademarked the Common UNIX Printing
            System, CUPS, and CUPS logo. These names and logos may be used
            freely in any direct port or binary distribution of CUPS. Please
            contract Easy Software Products for written permission to use
            them in derivative products. Our intention is to protect the
            value of these trademarks and ensure that any derivative product
            meets the same high-quality standards as the original.
            
            
            BINARY DISTRIBUTION RIGHTS
            
            Easy Software Products also sells rights to the CUPS source code
            under a binary distribution license for vendors that are unable
            to release source code for their drivers, additions, and
            modifications to CUPS under the GNU GPL and LGPL. For
            information please contact us at the address shown above.
            
            The Common UNIX Printing System provides a "pdftops" filter that
            is based on the Xpdf software. For binary distribution licensing
            of this software, please contact:

            SUPPORT
            
            Easy Software Products sells software support for CUPS as well
            as a commercial printing product based on CUPS called ESP Print
            Pro. You can find out more at our web site:
