Comprehensive TeX Archive Network
    The CTAN root directory
    This is the root of the Comprehensive
      TeX Archive Network directory tree. Most
      information in CTAN is contained in subdirectories:
    
      - 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
	(de
	fr
	uk)
	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:
	
	  - context
 -  The
	    ConTeXt distribution and contributed
	    material
 
	  - generic
 -  Macros that work in
	    several environments
 
	  - latex
 -  The
	    LaTeX distribution and
	    contributed material
 
	  
	  - plain
 -  Donald Knuth's example
	    macro set and contributed material
 
      
 
      - 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 structures macros.
 
      - support
 - 
	TeX support environments and the like
 
      - systems
 -  TeX
	systems; organised by operating environment, but also including:
	
	  - knuth
 - 
	    Donald Knuth's current distribution.
 
	  - generic
 - 
	    Complete systems that can potentially operate in more than one
	    operating environment.
 
	  - TeX
	    Live
 -  The Live collection of freely distributable TeX
	    material, including the TeX
	    Live on-line installer.
 
	  - 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
 
    
    CTAN on the Web
    CTAN can be found on the Web under the
     URL http://www.ctan.org. The CTAN team
     provides various features on this site:
    
    
    Searching CTAN
    You can search the content of the Catalogue with the following form on
      the CTAN site:
    
    
     In addition, CTAN archives maintain lists of their contents as plain
      text files, in a number of ways:
    
    
      - Sorted by
	  name (This is a big file…around 10M bytes).
 
      - New or changed in the last 7 days (This
	  is usually a more manageable size…)
 
    
    
    
      This is an experimental page. Comments,
	to the CTAN team, will be most
	welcome.
