\begin{description}
\item[Unix] The only current distribution of \TeX{} for Unix systems
  (including \acro{GNU}/Linux and other free Unix-like systems) is
  \texlive{}, which is distributed as part of the % ! line break
  \Qref*{\TeX{} collection}{Q-CD}.

  Members of many \TeX{} user groups receive copies of the collection
  (on \acro{DVD}), as part of their membership of the groups.

  MacOS/X is also a Unix-based system; however users should refer to
  the information below, under item ``Mac''.

  \texlive{} may also be installed ``over the network''; a network
  installer is provided, and once you have a system, a manager
  (\ProgName{tlmgr}) can both keep your installation up-to-date and
  add packages you didn't install at first.

  \begin{ctanrefs}
  \item[texlive]Browse \CTANref{texlive}
  \item[texlive installer (Unix)]\CTANref{texlive-unix}
  \end{ctanrefs}
\item[Linux] GNU/Linux users are supported by \texlive{} (as noted
  above).

  A free version of the commercial 
  \Qref*{V\TeX{} extended \TeX{} system}{Q-commercial} is available
  for use under Linux, which among other things specialises in direct
  production of \acro{PDF} from \AllTeX{} input.  Sadly, it's no
  longer supported, and the ready-built images are made for use with a
  rather ancient Linux kernel.

  For the future, the \miktex{} developer intends to release a version
  of that excellent (Windows) system for use on Linux; a beta version
  is available via \href{http://miktex.org/unx/}{the \miktex{} site}.
  \begin{ctanrefs}

  \item[vtex \nothtml{\rmfamily}required common files]\CTANref{vtex-common}
  \end{ctanrefs}
\item[\acro{PC}: Windows]
  \miktex{}, by Christian Schenk, is a comprehensive distribution.  It has
  its own previewer, \acro{YAP}, which is itself capable of printing,
  though the distribution also includes a port of \ProgName{dvips}.
  The current version is available for file-by-file download (the
  \acro{HTML} files in the directory offer hints on what you need to
  get going).  \miktex{} can automatically install packages that it
  ``knows about'', but that aren't in your system (it gets them over
  the network).  Furthermore, users may keep their installation
  up-to-date, over the network: the distribution contains a ``package
  manager'', through which the user may select individual packages, or
  request that every extant update be retrieved.

  \miktex{} may also be used in a configuration which involves no
  installation at all: its ``portable'' distribution may be unpacked
  on a memory stick, and used on any windows computer without making
  any direct use of the hard drive.  This is the first ``official''
  release of such a setup, though a similar object has been available
  on the net for some time.

  The \miktex{} developers also provide a ready-to-run copy of the
  distribution, on \acro{CD} (for purchase) via the % ! line break
  \href{http://www.miktex.org/cd/}{\miktex{} web site}; otherwise the
  \File{setup} executable is available on \acro{CTAN}, together with
  all the optional packages.
  
  \href{http://tug.org/protext/}{Pro\TeX{}t}, part of the \TeX{}
  collection by Thomas Feuerstack, is
  a further option for installing \miktex{}.  It bundles a \miktex{}
  setup with some further useful utilities, together with a \acro{PDF}
  file which contains clickable links for the various installation
  steps, along with explanations.

  Windows users are also supported directly by the \texlive{}
  distribution; a system is provided on the installation disc of the
  \TeX{} collection.  The system may also be installed over the
  network, using an installer application tailored for use with Windows.

  \href{http://foundry.supelec.fr/projects/xemtex/}{XEm\TeX{}}, by
  Fabrice Popineau (he who created the excellent, but now defunct,
  fp\TeX{} distribution), is an integrated distribution of \TeX{}, \LaTeX{},
  \CONTeXT{}, \ProgName{XEmacs} and friends for Windows.  All programs
  have been compiled natively to take the best advantage of the
  Windows environment.  Configuration is provided so that the
  resulting set of programs runs out-of-the-box.

  The (Japanese) \acro{W}32\acro{TEX} distribution was motivated by
  the needs of Japanese users (Japanese won't fit in a ``simple''
  character set like \acro{ASCII}, but \TeX{} is based on a version of
  \acro{ASCII}).  Despite its origins, \acro{W}32\acro{TEX} is said to
  be a good bet for Western users, notably those whose disks are short
  of space: the minimum documented download is as small as
  95\,MBytes.  Investigate the distribution at
  \URL{http://www.fsci.fuk.kindai.ac.jp/kakuto/win32-ptex/web2c75-e.html}

  A further (free) option arises from the
  \href{http://www.cygwin.com}{CygWin bundle}, which presents a
  Unix-like environment over the Win32 interface; an X-windows server
  is available.  If you run CygWin on your Windows machine, you have
  the option of using \texlive{}, too (you will need the X-server, to
  run \ProgName{xdvi}).  Of course, \texlive{} components will look like
  Unix applications (of course, that's presumably what you wanted),
  but \TeX{} under CygWin also reputedly somewhat slower than native
  Win32 implementations such as \miktex{} or XEm\TeX{}.  The (now
  obsolete) te\TeX{} distribution is provided as part of the CygWin
  distribution, and but you can build your own copy of \texlive{} from
  the current sources.

  BaKoMa \TeX{}, by Basil Malyshev, is a comprehensive (shareware)
  distribution, which focuses on support of Acrobat.  The distribution
  comes with a bunch of Type~1 fonts packaged to work with BaKoMa
  \TeX{}, which further the focus.

\item[\acro{PC}: \MSDOS{} or \acro{OS/}2] Em\TeX{}, by Eberhard Mattes,
  includes \LaTeX{}, \BibTeX{}, previewers, and drivers, and is
  available  as a series of zip archives.  Documentation is
  available in both German and English.  Appropriate memory managers
  for using em\TeX{} with 386 (and better) processors and under
  Windows, are included in the distribution.  Em\TeX{} will operate
  under Windows, but Windows users are better advised to use a
  distribution tailored for the Windows environment.

  A version of em\TeX{}, packaged to use a
  % beware line break
  \Qref*{TDS directory structure}{Q-tds}, is separately available as
  an em\TeX{} `contribution'.  Note that neither em\TeX{} itself, nor
  em\TeX{}\acro{TDS}, is maintained.  Most users of Microsoft
  operating systems, who want an up-to-date \AllTeX{} system, need to
  migrate to Win32-based systems.

\item[\acro{PC}: \MSDOS{}] The most recent \MSDOS{} offering is a
  port of the Web2C~7.0 implementation, using the \acro{GNU}
  \ProgName{djgpp} compiler.  While this package is more recent than
  em\TeX{}, it still implements a rather old instance of \AllTeX{}.

\item[\acro{PC}: \acro{OS/}2] Em\TeX{}, by Eberhard Mattes (see
  above), was actually developed under \acro{OS/}2, and lives happily
  in that environment.

  \acro{OS/}2 users may also use a free version of the
  commercial \Qref*{V\TeX{}}{Q-commercial}, which specialises
  in direct production of \acro{PDF} from \AllTeX{} input.  (This
  version is, like the Linux version, unfortunately no longer supported.)

\item[Mac] \href{http://www.trevorrow.com/oztex/}{Oz\TeX{}}, by Andrew
  Trevorrow, is a shareware version of
  \TeX{} for the Macintosh.  A \acro{DVI} previewer and \PS{}
  driver are also included.  (Members of \acro{UK}~\acro{TUG} may
  acquire the software without further payment, as part of a
  membership deal.)  Oz\TeX{} does not run, natively, under MacOS/X,
  but will run with a sufficiently recent CarbonLib (see
  \URL{http://www.trevorrow.com/oztex/ozosx.html}).
  Other questions about Oz\TeX{} itself may be directed to
  \mailto{oztex@midway.uchicago.edu}

  Another partly shareware program is
  \href{http://www.kiffe.com/cmactex.html}{CMac\TeX{}} , put together
  by Tom Kiffe.  CMac\TeX{} is much closer than Oz\TeX{} to the Unix
  \TeX{} model of things (it uses \ProgName{dvips}, for instance).
  CMac\TeX{} runs natively under  includes a port of a version of
  \Qref*{Omega}{Q-omegaleph}.

  Both Oz\TeX{} and \acro{CM}ac\TeX{} run on either MacOS/X or on a
  sufficiently recent MacOS with CarbonLib 
  (v1.3~for Oz\TeX{}, v1.4~for CMac\TeX{}).

\Question[Q-editors]{\TeX{}-friendly editors and shells}

There are good \TeX{}-writing environments and editors for most
operating systems; some are described below, but this is only a
personal selection:
\begin{description}
\item[Unix] The commonest choices are \ProgName{[X]Emacs} or
  \ProgName{vim}, though several others are available.
  
  \href{http://www.gnu.org/software/emacs/emacs.html}{\acro{GNU}\nobreakspace\ProgName{emacs}}
  and \href{http://www.xemacs.org/}{\ProgName{XEmacs}} are supported
  by the \acro{AUC}-\TeX{}
  bundle (available from \acro{CTAN}).  \acro{AUC}-\TeX{} provides menu
  items and control sequences for common constructs, checks syntax,
  lays out markup nicely, lets you call \TeX{} and drivers from
  within the editor, and everything else like this that you can think
  of.  Complex, but very powerful.

  \href{http://vim.sourceforge.net}{\ProgName{Vim}} is also highly
  configurable (also available for Windows and Macintosh systems).
  Many plugins are available to support the needs of the \AllTeX{} user,
  including syntax highlighting, calling \TeX{} programs,
  auto-insertion and -completion of common \AllTeX{} structures, and
  browsing \LaTeX{} help.  The scripts \File{auctex.vim} and
  \File{bibtex.vim} seem to be the most common recommendations.

  The editor \href{http://nedit.org/}{\ProgName{NEdit}} is also free
  and programmable, and is available for Unix systems.  An
  \acro{AUC}-\TeX{}-alike set of extensions for \ProgName{NEdit} is available
  from \acro{CTAN}.

  \ProgName{LaTeX4Jed} provides much enhanced \LaTeX{} support for the
  \href{http://www.jedsoft.org/jed/}{\ProgName{jed}} editor.
  \ProgName{LaTeX4Jed} is similar to \acro{AUC}-\TeX{}: menus,
  shortcuts, templates, syntax highlighting, document outline,
  integrated debugging, symbol completion, full integration with
  external programs, and more. It was designed with both the beginner
  and the advanced LaTeX user in mind.

  The \ProgName{Kile} editor that is provided with the \acro{KDE}
  window manager provides \acro{GUI} ``shell-like'' facilities, in a
  similar way to the widely-praised \ProgName{Winedt} (see below);
  details (and downloads) are available from the project's
  \href{http://kile.sourceforge.net/}{home on SourceForge}.  A newer
  system (by \ProgName{Kile}'s original author),
  \href{http://www.xm1math.net/texmaker/}{\ProgName{texmaker}} doesn't
  rely on \acro{KDE}'s facilities, and so may be more easily portable.
\item[\MSDOS{}] \TeX{}shell is a simple,
  easily-customisable environment, which can be used with the editor
  of your choice.

  You can also use \acro{GNU}~\ProgName{emacs} and \acro{AUC}-\TeX{}
  under \MSDOS{}.
\item[Windows '9x, NT, etc.]\ProgName{TeXnicCenter} is a (free)
  \TeX{}-oriented development system, uniting a powerful platform for
  executing \AllTeX{} and friends with a configurable editor.
  
  \ProgName{Winedt}, a shareware package, is also highly spoken of.
  It too provides a shell for the use of \TeX{} and related programs,
  as well as a powerful and well-configured editor.  The editor can
  generate its output in \acro{UTF}-8 (to some extent), which is
  useful when working with \Qref*{\xetex{}}{Q-xetex} (and other
  ``next-generation'' \AllTeX{} applications).

  Both \ProgName{emacs} and \ProgName{vim} are available in versions
  for Windows systems.
\item[\acro{OS/}2] \ProgName{epmtex}  offers an \acro{OS/}2-specific shell.
\item[Macintosh] The commercial Textures provides an excellent integrated
  Macintosh environment with its own editor.  More powerful still (as an
  editor) is the shareware \ProgName{Alpha} which is
  extensible enough to let you perform almost any \TeX{}-related job. It
  works well with Oz\TeX{}.  From release 2.2.0 (at least), Textures
  works with MacOS~X.

  For MacOS~X users, the free tool of choice appears to be
  \href{http://www.uoregon.edu/~koch/texshop/texshop.html}{\texshop{}}, which
  combines an editor and a shell with a coherent philosophy of dealing
  with \AllTeX{} in the OS~X environment.  TeXShop is distributed as
  part of the MacTeX system, and will therefore be available out of
  the box on machines on which MacTeX has been installed.

  \ProgName{Vim} is also available for use on Macintosh systems.
\item[Wildcard] \acro{TUG} is sponsoring the development of a
  cross-platform editor and shell, modelled on the excellent
  \texshop{} for the Macintosh.  While this program,
  \href{http://www.tug.org/texworks/}{\texworks{}}, is still under
  development, it is already quite usable: if you're looking for a
  \AllTeX{} development environment, and are willing to step beyond
  the boundaries, it may be for you.
\end{description}
Atari, Amiga and \acro{N}e\acro{XT} users also have nice
environments. \LaTeX{} users looking for \ProgName{make}-like
facilities should review the answer on
\Qref*{Makefiles for \LaTeX{} documents}{Q-make}.

While many \AllTeX{}-oriented editors can support work on \BibTeX{}
files, there are many systems that provide specific ``database-like''
access to your \BibTeX{} files~---
\begin{wideversion}
  see ``\Qref{creating a bibliography file}{Q-buildbib}''.
\end{wideversion}
\begin{narrowversion}
  these are discussed in % ! line break
  ``\Qref*{creating a bibliography file}{Q-buildbib}''.

\Question[Q-commercial]{Commercial \TeX{} implementations}
\keywords{windows,macintosh,commercial}

There are many commercial implementations of \TeX{}. The first
appeared not long after \TeX{} itself appeared.

What follows is probably an incomplete list.  Naturally, no warranty or
fitness for purpose is implied by the inclusion of any vendor in this
list.  The source of the information is given to provide some clues to
its currency.

In general, a commercial implementation will come `complete', that is,
with suitable previewers and printer drivers.  They normally also have
extensive documentation (\emph{i.e}., not just the \TeX{}book!) and some
sort of support service.  In some cases this is a toll free number
(probably applicable only within the \acro{USA} and or Canada), but others
also have email, and normal telephone and fax support.
