LyX - A WYSIWYM document processor. LyX is a document processor that encourages an approach to writing based on the structure of your documents (WYSIWYM) and not simply their appearance (WYSIWYG). LyX combines the power and flexibility of TeX/LaTeX with the ease of use of a graphical interface. This results in world-class support for creation of mathematical content (via a fully integrated equation editor) and structured documents like academic articles, theses, and books. LyX requires a working installation of TeX/LaTeX. For this you may install Texlive packages available here or from Texlive DVD. WARNING: Note that tetex, the TeX package in the base Slackware distribution was abandoned more than 10 years ago and needs to be replaced with the latest version of Texlive for best experience with LyX.
