## About Fontmatrix

Fontmatrix is a free and open-source font management application for Linux and other Unix-like operating systems. Released under the GNU General Public License version 2 (GPLv2), it provides users with a comprehensive toolset for browsing, previewing, organizing, and activating fonts.

The project was born from the need for a dedicated font manager in the free software ecosystem. While proprietary operating systems have long offered font management tools, Linux users historically relied on manual fontconfig editing and command-line utilities. Fontmatrix fills that gap with a graphical interface that respects the Unix philosophy.
