TeX Live is a free software distribution for the TeX typesetting system that includes major TeX-related programs, macro packages, and fonts. It is the replacement of its no-longer supported counterpart teTeX. It is now the default TeX distribution for several Linux distributions such as Fedora, Debian, Ubuntu and Gentoo. Other Unix operating systems like OpenBSD, FreeBSD and NetBSD have also converted from teTeX to TeX Live.
