Licensing Information
Open Source Used In Cisco ISSI Gateway 4.8(1) 609
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 and CUPS Imaging libraries
located in the "cups" and "filter" subdirectories 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.
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.
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 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 and CUPS Imaging libraries
under other licenses and/or conditions as appropriate for your
application, driver, or filter.
