'''L^AT_<big>E</big>X''', written as '''LaTeX''' in plain text, is a [[document preparation system]] for the [[TeX]] [[typesetting]] program.

'''[[Audacity (audio editor)|Audacity]]''' is a [[digital audio editor]] and recording application. Audacity is [[cross-platform]] and is

available for [[Microsoft Windows|Windows]], {{nowrap|[[Mac OS X]]}},

It offers programmable [[desktop publishing]] features and extensive facilities for automating most aspects of [[typesetting]] and desktop publishing, including numbering and cross-referencing, tables and figures, page layout, [[bibliography|bibliographies]], and much more. LaTeX was originally written in [[1984]] by [[Leslie Lamport]] and has become the dominant method for using [[TeX]]&mdash;few people write in plain TeX anymore. The current version is LaTeX2ε. Both LaTeX and TeX are [[free software]].

LaTeX is based on the idea that ''authors'' should be able to concentrate on ''writing'' within the logical structure of their document, rather than spending their time on the details of ''formatting''.

others around the world. The latest beta release of Audacity is 1.3.14

Because the author specifies the logical structure of the document, and lets the LaTeX system worry about the presentation, it is often regarded as superior to [[word processor]]s and most other desktop publishing systems, which allow trivially easy visual layout changes but tend to intertwine content and form so tightly that consistency and automation are often difficult. LaTeX also provides great flexibility in formatting while maintaining the identity of structure, which purely structural systems like [[SGML]] and [[XML]] do not directly address.

For example, there are numerous commercial implementations of the whole TeX system (which includes LaTeX), and vendors may offer extra features like phone support and additional [[typeface]]s.

LaTeX is distributed under a [[free software licence]], the [[LaTeX Project Public License]] (LPPL). The LPPL is not compatible with the [[GNU General Public License]], as it requires that modified files indicate that they have been modified in some way; this was done to ensure that files that depend on other files will produce the expected behavior and avoids problems similar to [[DLL hell]]. The LPPL is [[Debian Free Software Guidelines|DFSG]] compliant since its version 1.3.
