[#] 6 [GPLv2] 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. [GPLv3] 
Non-Source Distribution. You may copy and distribute a covered work in Object Code form under the terms of Sections 4 and 5, provided that you also distribute the machine-readable Complete Corresponding Source Code (herein the "Corresponding Source") under the terms of this License, in one of these ways: a) Distribute the Object Code in a physical product (including a physical distribution medium), accompanied by the Corresponding Source distributed on a durable physical medium customarily used for software interchange; or, b) Distribute the Object Code in a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give any third party, for a price no more than ten times your cost of physically performing source distribution, a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange; or, c) Privately distribute the Object Code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only for occasional noncommercial distribution, and only if you received the Object Code with such an offer, in accord with Subsection b above. Or, d) Distribute the Object Code by offering access to copy it from a designated place, and offer equivalent access to copy the Corresponding Source in the same way through the same place. You need not require recipients to copy the Corresponding Source along with the Object Code. [If the place to copy the Object Code is a network server, the Corresponding Source may be on a different server that supports equivalent copying facilities, provided you have explicitly arranged with the operator of that server to keep the Corresponding Source available for as long as needed to satisfy these requirements, and provided you maintain clear directions next to the Object Code saying where to find the Corresponding Source.] Distribution of the Corresponding Source in accord with this section must be in a format that is publicly documented, unencumbered by patents, and must require no special password or key for unpacking, reading or copying. The Corresponding Source may include portions which do not formally state this License as their license, but qualify under section 7 for inclusion in a work under this License.
