Editing LaTeX (section)

== Licensing ==
LaTeX is typically distributed along with plain [[TeX]] under a [[free software license|free software licence]]: the [[LaTeX Project Public License]] (LPPL).<ref>{{Cite web |title=The LaTeX project public license |url=https://www.latex-project.org/lppl/ |access-date=2019-07-20 |website=www.latex-project.org}}</ref> The LPPL is not [[License compatibility|compatible]] with the [[GNU General Public License]], as it requires that modified files must be clearly differentiable from their originals (usually by changing the filename); this was done to ensure that files that depend on other files will produce the expected behavior and avoid [[dependency hell]]. The LPPL is [[Debian Free Software Guidelines]] (DFSG) compliant as of version 1.3. As [[free software]], LaTeX is available on most operating systems, which include [[Unix]] ([[Oracle Solaris|Solaris]], [[HP-UX]], [[AIX]]), [[BSD]] ([[FreeBSD]], [[macOS]], [[NetBSD]], [[OpenBSD]]), [[Linux]] ([[Red Hat Enterprise Linux|Red Hat]], [[Debian]], [[Arch Linux|Arch]], [[Gentoo Linux|Gentoo]]), [[Microsoft Windows|Windows]], [[DOS]], [[RISC OS]], [[AmigaOS]], and [[Plan 9 from Bell Labs|Plan 9]].
