original question: How many web browsers are open-sourced under [GNU General Public License] and support programming languages designed by [Dennis Ritchie]?
answer: 5
answer type: Web browser.
auxiliary information: The GNU General Public License is the most widely used free software license, which guarantees end users the freedoms to run, study, share, and modify the software. Software that allows these rights is called free software and, if the software is copylefted, requires those rights to be retained. The GPL demands both. The license was originally written by Richard Stallman of the Free Software Foundation for the GNU project. In other words, the GPL grants the recipients of a computer program the rights of the Free Software Definition and uses copyleft to ensure the freedoms are preserved whenever the work is distributed, even when the work is changed or added to. The GPL is a copyleft license, which means that derived works can only be distributed under the same license terms. This is in distinction to permissive free software licenses, of which the BSD licenses and the MIT License are the standard examples. GPL was the first copyleft license for general use. As of August 2008, the GPL accounted for 60.5% of the 44,927 free software projects listed on Freecode, and as of 2003, about 68% of the projects listed on SourceForge.net.Dennis Ritchie:;Type: Programming Language Designer. ;
