Please answer the following question: Information:  - Metafont is a description language used to define vector fonts. It is also the name of the interpreter that executes Metafont code, generating the bitmap fonts that can be embedded into e.g. PostScript. Metafont was devised by Donald Knuth as a counterpart to his TeX typesetting system.  - LaTeX (, also pronounced as , a shortening of Lamport TeX) is a document preparation system. When writing, the writer uses plain text as opposed to formatted text, as in WYSIWYG word processors like Microsoft Word or LibreOffice Writer. The writer uses markup tagging conventions to define the general structure of a document (such as article, book, and letter), to stylise text throughout a document (such as bold and italic), and to add citations and cross-references. A TeX distribution such as TeX Live or MikTeX is used to produce an output file (such as PDF or DVI) suitable for printing or digital distribution. Within the typesetting system, its name is stylised as LaTeX.  - WYSIWYG is an acronym for "what you see is what you get". In computing, a WYSIWYG editor is a system in which content (text and graphics) can be edited in a form closely resembling its appearance when printed or displayed as a finished product, such as a printed document, web page, or slide presentation.  - BibTeX is reference management software for formatting lists of references . The BibTeX tool is typically used together with the LaTeX document preparation system . Within the typesetting system , its name is styled as ( \ mathrm ( B ( \ scriptstyle ( IB ) ) \ ! T \ ! -- ( \ displaystyle E ) \ ! X ) ) . The name is a portmanteau of the abbreviation of `` bibliography '' and TeX . BibTeX makes it easy to cite sources in a consistent manner , by separating bibliographic information from the presentation of this information , similarly to the separation of content and presentation / style supported by LaTeX itself .  - TeX (or , see below) is a typesetting system (or "formatting system") designed and mostly written by Donald Knuth and released in 1978. Together with the Metafont language for font description and the Computer Modern family of typefaces, TeX was designed with two main goals in mind: to allow anybody to produce high-quality books using minimal effort, and to provide a system that would give exactly the same results on all computers, at any point in time. TeX is free software, which has made it more accessible to a wider range of users.  - X (named "ex" , plural "exes") is the 24th and antepenultimate letter in the modern English alphabet and the ISO basic Latin alphabet.  - Computer Modern is the original family of typefaces used by the typesetting program TeX. It was created by Donald Knuth with his Metafont program, and was most recently updated in 1992. Computer Modern, or variants of it, remains very widely used in scientific publishing, especially in disciplines that make frequent use of mathematical notation.  - TeX Live is a free software distribution for the TeX typesetting system that includes major TeX-related programs, macro packages, and fonts. It is the replacement of its no-longer supported counterpart teTeX. It is now the default TeX distribution for several Linux distributions such as openSUSE, Fedora, Debian, Ubuntu and Gentoo. Other Unix operating systems like OpenBSD, FreeBSD and NetBSD have also converted from teTeX to TeX Live.  - MiKTeX is a distribution of the TeX/LaTeX typesetting system for Microsoft Windows. It also contains a set of related programs. MiKTeX provides the tools necessary to prepare documents using the TeX/LaTeX markup language, as well as a simple tex editor: TeXworks. The name comes from Christian Schenk's login: MiK for Micro-Kid.    What is the relationship between 'bibtex' and 'web'?
