GNU

GNU
GNU is a Unix-like operating system that is free software—it respects your freedom. You can install Linux-based versions of GNU which are entirely free software. The GNU System provides a collection of applications, libraries, and developer tools, plus a program to allocate resources and talk to the hardware, known as a kernel. For a complete list of GNU packages and more, visit gnu.org/software.

This is an automatically-generated list of all (368) GNU packages indexed by the Free Software Directory.

These GNU packages are looking for a maintainer. Check the list of decommissioned GNU packages if you have time and interest in resurrecting one. Also, Womb is a collective repository for random code that isn't ready to become a separate GNU project, or intends to be merged with an already existing GNU project.
