LyX is a WYSIWYM (what you see is what you mean) tool, frontend for LaTeX wnich allows users with no programming knowledge to get the full benefits of LaTeX.

LyX differs from products such as TeTeX as one needs to know no code and can simply write and mark any text as a footnote of chapter heading etc., and then hit the PDF button to get a perfectly formatted output.

LyX is a document processor that encourages an approach to writing based on the structure of your documents, not their appearance. It is released under a Free Software / Open Source license.

LyX is for people that write and want their writing to look great, right out of the box. No more endless tinkering with formatting details, 'finger painting' font attributes or futzing around with page boundaries. You just write. In the background, Prof. Knuth's legendary TeX typesetting engine makes you look good.

On screen, LyX looks like any word processor; its printed output --or richly cross-referenced PDF, just as readily produced -- looks like nothing else. Gone are the days of industrially bland .docs, all looking similarly not-quite-right, yet coming out unpredictably different on different printer drivers. Gone are the crashes 'eating' your dissertation the evening before going to press.

LyX is stable and fully featured. It is a multi-platform, fully internationalized application running natively on Unix/Linux, the Macintosh and modern Windows platforms.

Here are some key features of "LyX":

· Graphical User Interface that gives access to all functions via menus and mouse, as well as configurable keybindings
· Standard word processor operations, like cut/paste, multiple open documents, infinite undo/redo, spellchecking (uses ispell in the background)
· Different textclasses allow you to type letters, articles, books, movie scripts, LinuxDoc, slides. Also included are some textclasses for scientific societies, such as AMS, APS, IEEE, or specific journals like Astronomy and Astrophysics.
· Numbered section headings, table of contents (with hypertext functionality), nested lists (aka "outline mode")
· Interactive WYSIWYG math editor
· Support for writing documents in most European languages, as well as Right-to-Left languages like Hebrew and Arabic, including multi-lingual documents.
· Postscript figures, with rotation, scaling, and captions
· Interactive WYSIWYG tables
· Footnotes and margin notes
· Labels/references and bibliography (including BibTeX support)
· Access to all LaTeX functionality with plain-latex-style
· Import LaTeX. Export LaTeX, Postscript®, DVI, ASCII, or send a fax
· SGML-tools support (both LinuxDoc and DocBook DTDs)
· Literate programming support, via the "noweb" tool.
· Menus, error messages, and keybindings are available in many languages
· Extensive documentation, including a beginner's tutorial. Some docs have been translated from English.

Requirements:

· teTeX installation.

· After an inset, don't always revert to the language's default encoding for latex output, but honor that specified in the document settings (bug 4665).
· Close font macros (such as emph) before comments, greyedout, framed and shaded notes, thus fixing a problem where documents couldn't be compiled anymore.

· Fix LaTeX errors triggered by switching from ams article to ams plain article.

· Fix loading of lyx documents generated with csv2lyx (bug 4639).
· Move label{} outside of listings option caption={} because the listings package prefers a separate label={} option.

· correct numbering inside multiline environments (bug 518).
· Fix typo in the script TeXFiles.py that scans for TeX files.
