Section 13 GPLv3 discribes, how to use or combine covered work with work licensed under the GNU Affero General Public license. The GNU Affero General Public License is a free, copyleft license for software and other kinds of works, specifically designed to ensure cooperation with the community in the case of network server Software (Free Software Fundation http://www.gnu.org/licenses/agpl-3.0.de.html Everyone is permitted by the copyright holder, to copy and distribute verbatim copies of the copyright license document. Changing the copyright-agreement, is not allowed.) The GNU Affero General Public License, often abbreviated as Affero GPL and AGPL (and sometimes informally called the Affero License), refers to two distinct, though historically related, free software licenses: The Affero General Public License, version 1 which was published by Affero, Inc. in March 2002, and is based on the GNU General Public License, version 2 (GPLv2), and also the GNU Affero General Public License, version 3, published by the Free Software Foundation in November 2007, and based on the GNU General Public License, version 3 (GPLv3). Both versions of the AGPL were designed to close a perceived application service provider “loophole” (the “ASP loophole”) in the ordinary GPL, where, by using but not distributing the software, the copyleft provisions are not triggered. Each version differs from the version of the GNU GPL on which it is based in having an additional provision addressing use of software over a computer network. The additional provision requires that the complete source code be made available to any network user of the AGPL-licensed work, typically a Web application. The Free Software Foundation has recommended that the GNU AGPLv3 be considered for any software that will commonly be run over a network.[2] The Open Source Initiative approved the GNU AGPLv3[3] as an open source license in March 2008 after the company Funambol submitted it for consideration.[7]

It does that, in the following way:
13. Use with the GNU Affero General Public License.
Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the special requirements of the GNU Affero General Public License, section 13, concerning interaction through a network will apply to the combination as such.
