README.structure ================ This file describes the structure of the CTAN archives. The Comprehensive TeX Archive Network (CTAN) is a set of nodes that maintain a collection of freely-available material in support of users of the TeX typesetting system by Donald Knuth, or of directly related systems (such as developments of, or extensions to, TeX). The archive is organised as a small set of directory hierarchies, most of which have content directly related to an identifiable function needed by the TeX user. The top level of the archive tree contains README.* files (such as the present file), and the FILES.* indexes. Its subtrees are: biblio/ Systems for maintaining and presenting bibliographies within documents typeset using TeX digests/ Collections of TeX mailing list digests, TeX-related `electronic magazines', and indexes, etc., of printed publications dviware/ Printer drivers and previewers, etc., for .dvi files fonts/ Fonts written in Metafont, and support for using fonts from other sources (e.g., those in Adobe Type 1 format) graphics/ Systems and TeX macros for producing graphics help/ FAQs and similar direct assistance; the catalogue indexing/ Systems for maintaining and presenting indexes of documents typeset using TeX. info/ Manuals and extended how-to information; errata for TeX- related publications, collections of project (e.g., LaTeX and NTS) documents, etc. install/ ZIP files of ready-to-install CTAN packages. The package contained in CTAN directory a/b/c/d/ appears as install/a/b/c/d.tds.zip - each such file may be unzipped directly into a TDS tree, and should contain no ``tree prefix'' language/ Support for various languages; hyphenation patterns macros/ TeX macros; several directories have significant sub-trees: macros/context/ The ConTeXt distribution and contributed material macros/generic/ Macros that work in several environments macros/latex/ The LaTeX distribution and contributed material macros/luatex/ Macros that require the LuaTeX engine macros/plain/ Donald Knuth's original plain TeX format, and contributions macros/xetex/ Macros that require the XeTeX engine obsolete/ Material which is now obsolete, but which needs to remain on the archive for some reason (such as the 1992 LaTeX 2.09 distribution). The tree maintains a `shadow hierarchy' - for example, obsolete/macros/ has the same basic structure as macros/. support/ TeX support environments and the like systems/ TeX systems; organised by operating environment, but also including: systems/knuth/ Donald Knuth's current distribution systems/generic/ Complete systems that can potentially operate in more than one operating environment systems/mac/mactex/ The distribution of MacTeX for Mac OS X systems/texlive/ The Live collection of freely distributable TeX material, including the TeX Live on-line installer systems/win32/miktex/ The distribution of MiKTeX; CTAN provides a home for MiKTeX's package repository, part of its online installer. tds/ The TeX Directory Structure standard (the output of the TUG TDS working group) usergrps/ Information supplied by TeX User Groups web/ `Literate Programming' tools and systems
