Software Table of Contents Introduction How To Get GNU Software Descriptions of GNU Software Packages GNU Java programs Descriptions of some Other GPL-Covered Free Software Packages Descriptions of some Other Non-GPL-Covered Free Software Packages Introduction This is a list of most GNU software. We would like to list all GNU programs here, but that will take more work. If you would like to write descriptions for other GNU programs, here's what to do! We also maintain a list of software that is not part of the GNU Project but which we feel are important to mention and a page about Year 2000 issues with GNU software. If you're looking for a list of GNU projects or other free software related projects, please look at our projects page. If you are interested in contributing to GNU Projects, Please have a look at our help-wanted page. If you want to buy a new computer, you might want to consider one of these companies who sell computers with wholly free systems preinstalled. For a description of GNU Licenses, please look at Licenses page. How To Get GNU Software GNU software is available by several different methods: Buy copies on CD-ROM from the FSF. This helps provide the funds for the GNU Project. Our three CD-ROM sets include source code for all GNU software, GNU compiler tools executable on ten common platforms, and a larger selection executable on intel-microsoft platforms. Get it by FTP. By FTP we provide source code for all GNU software, free of charge. (Please also make a donation to the FSF, if you can, to help us write more free software.) Get a copy from a friend. (Please also make a donation to the FSF, if you can, to help us maintain free software.) Buy a computer with a wholly free GNU/Linux system preinstalled from one of the companies that can offer this.
