Additional information is taken from original documentation of the software and some review articles.

This will try to explain them very shortly: +\begin{description} +\item[editor] Typically, a user interfaces with any *\TeX\ via an editor as a front end. Although they might look fancy with a lot of graphical interfaces, an editor is just a program that allows the user to create and change a text file. This can be done with any program, but specialized editors offer additional features. It is important to keep in mind that an editor alone can \emph{not} convert a \verb|.tex| file into a pdf or any other output format, but always needs the programs as discussed below, most notably an engine that does all the work. This might often be hidden from the user's direct view by buttons which offer convenient ways to execute everything that is necessary. +\item[engine] This is the program that does all the actual work. The original program is \TeX, the most famous derivative is pdf\TeX, while Lua\TeX\ is the latest successor. Normally,~a~user does not interface directly with the program, but uses an editor to parse a text file to it. +\item[format] A format is a (large) collection of abbreviations (macros) that make the life easy when working with \TeX. The most commonly used formats are \LaTeX, Con\TeX t and plain\TeX. The latter one is a minimal set of macros provided by Don Knuth. Formats can be combined with different engines, exploiting the special abilities of these engines. A format is in the beginning a collection of text files, but can be compiled into a binary format that can be read much faster by the engine. +\item[distribution] In addition to formats, a large set of supplementary files can be used to work with \TeX, called \emph{packages} for \LaTeX, \emph{modules} for Con\TeX t, and many external programs have proven useful for the work with \TeX. Distributions such as \TeX~Live and MiK\TeX\ strive to provide a full set of such programs and macros by using a package manager to take care of package dependencies and updating. Many Linux distributions, as well as cygwin for Windows, repackage a \TeX\ distribution (mostly \TeX~Live) using the Linux distribution's package system. +\end{description} + +\newpage +\section{How to read this document} +This document consists of several graphs showing the development of software more or less directly related to \TeX. The graphs try to show the time development (downwards), as well as dependencies, changes, etc. + +I tried to make the graphs more readable by using colors for different categories. The decisions about what is important and what is “normal” reflect my personal opinion only. + +\begin{description} +\item[{\let\nodecolor\normalimportant \tikz \node[coolnode]{normal};}] That is, not very important in my opinion, no huge user group, but still maybe important for special needs. Was used by a major community at least some time back, but is not of great impact nowadays. + +\item[{\let\nodecolor\vip \tikz \node[coolnode]{important};}] Engines or formats that had or have a great impact on (everyday) typesetting for a large community. + +\item[{\let\nodecolor\experimental \tikz \node[coolnode]{experimental};}] Developments that might still be under construction or were never used by a large community. Nevertheless, these might be very important to the development of other engines or for use of special typesetting. + +\item[{\let\nodecolor\planned \tikz \node[coolnode]{planned};}] Things that are planned to raise one day and are in the phase of preparation, i.\,e. there may be some code but not in the final form yet. + +\item[{\let\nodecolor\package \tikz \node[coolnode]{package};}] \LaTeX-packages or single \TeX-files (useable as packages or modules) that seemed worth mentioning. There won't be many of this; just some that might elsewise be confused for something else. + +\item[{\let\nodecolor\distro \tikz \node[coolnode]{distribution};}] Software bundles that bring \TeX\ and friends to the normal user. + +\item[{\let\nodecolor\histdistro \tikz \node[coolnode]{hist. dist.};}] Historical distributions that have no use today but were important for bringing \TeX\ to older computer systems. + +\item[{\let\nodecolor\program \tikz \node[coolnode]{program};}] Programs that are not directly connected to \TeX\ (but interesting in the context of using \TeX) or separate helper programs. + +\item[{\let\nodecolor\fonttechnology \tikz \node[coolnode]{font};}] Something related to a font. Neither a program nor libraries that provide access to fonts nor the actual files, but rather the abstract definition or specification. + +\end{description} + +Some of the graphs have quite many entries, which is the reason why there are two versions of them: A short one listing only the most important things and a full version with everything I could find. + +In most cases I did not mention the authors of the programs/packages. This is not to diminish their effort but only for brevity (long names make things harder to read). I did not write any of the below-mentioned programs or packages. The authors are given in the documents linked in the references. + +\section{How to contribute} +I hope one day this document would become the standard reference for questions like ”Which program do I need for~…?“, ”What's the difference between …\TeX\ and …\TeX?“, ”Why is it called …?“ etc. + +To get to this point, I need some help of people who know more about the \TeX\ world than I do. It is up to you to contribute texts, references, links, descriptions, hints etc. I'll be happy about anything I can add here. Also, if you have suggestions about the layout or corrections to the content, let me know. + +\newpage +\section{Problems with PDF viewers} +This document shows additional information via tooltips. At least that's what it should do. Unfortunately, there is no unique way to get hover-over tooltips to work in all PDF viewers, but each of them has its own way to present the information. For now, the information are provided as a hyperlink which points nowhere meaningful. But most viewers can shows this information in a way the user can understand. + +The following list summarizes my experience with different PDF viewers, all but the Adobe Reader XI tested on an Arch Linux. Your experince might differ; if you have any annotations to this list, I'll happily add them – especially if the document breaks anything completely. + +\begin{description} +\item[evince 3.20.0] Shows the document correctly and completely. + +\item[Adobe Reader 9] Shows the document correctly and completely, surprisingly. + +\item[Adobe Reader XI] Shows the document correctly and completely, surprisingly.

Ignore those and it's fine. + +\item[okular 0.25.0] As \TeX works, but does not break the tooltips, therefore information is lost. + +\item[xpdf 3.04] Shows the tooltips only in the status bar, thus hiding most of the information in the graphs. + +\end{description} + +\subsection*{About this document} +This document is typeset in the \TeX\ Gyre Pagella font using the Lua\LaTeXe\ format with \verb|expl3| and \verb|xpackages| based on Lua\TeX\ 0.\the\luatexversion.\luatexrevision. + +In case you wonder why the typesetting is so ugly, especially the margins: Those are chosen to be small so that much text fits on one page which in this case increases the overview. I do not expect anybody to ever print this document, therefore I ignore the need of margins.
