       aleph - extended unicode TeX


       aleph [options] [& format ] [ file | \ commands ]


       Run  the  Aleph  typesetter on file, usually creating file.dvi.  If the
       file argument has no extension, ".tex" will be appended to it.  Instead
       of a filename, a set of Aleph commands can be given, the first of which
       must start with a backslash.  With a  &format  argument  Aleph  uses  a
       different  set  of precompiled commands, contained in format.fmt; it is
       usually better to use the -fmt format option instead.

       Aleph is a  version  of  the  TeX  program  modified  for  multilingual
       typesetting.  It uses unicode, and has additional primitives for (among
       other things) bidirectional typesetting.

       The inialeph and viraleph commands are Aleph's analogues to the  initex
       and  virtex  commands.   In this installation, they are symlinks to the
       aleph executable.

       Aleph's command line options are similar to those of TeX.

       Aleph is experimental software.


       Run aleph --help to see the complete  list  of  options;  this  is  not

              Exit  with  an  error  code  when an error is encountered during

       --help Print help message and exit.

       --ini  Be `initial' Aleph for dumping formats; this is implicitly  true
              if the program is called as inialeph.

       --interaction mode
              Sets  the  interaction  mode.  The mode can be one of batchmode,
              nonstopmode, scrollmode,  and  errorstopmode.   The  meaning  of
              these  modes is the same as that of the corresponding \commands.

       --ipc  Send DVI output to a socket as well as the  usual  output  file.
              Whether this option is available is the choice of the installer.

              As --ipc, and starts the  server  at  the  other  end  as  well.
              Whether this option is available is the choice of the installer.

       --kpathsea-debug bitmask
              Sets path searching debugging flags according  to  the  bitmask.
              See the Kpathsea manual for details.

       --maketex fmt
              Enable mktexfmt, where fmt must be one of tex or tfm.

       --no-maketex fmt
              Disable mktexfmt, where fmt must be one of tex or tfm.

       --output-comment string
              Use string for the DVI file comment instead of the date.

       -output-directory directory
              directory instead of the current directory.  Look up input files
              in directory first, the along the normal search path.

              If the first line of the main input file begins with %& parse it
              to look for a dump name.

       --progname name
              Pretend  to  be program name.  This affects both the format used
              and the search paths.

              Enable the filename recorder.  This leaves a trace of the  files
              opened  for  input  and  output  in  a file with extension .ofl.
              (This option is always on.)

              Enable the \write18{command} construct.  The command can be  any
              Bourne  shell command.  By default, this construct is enabled in
              a restricted mode, for security reasons.

              Print version information and exit.


       See the Kpathsearch library documentation  (the  `Path  specifications'
       node)  for  precise  details of how the environment variables are used.
       The kpsewhich utility can be used to query the values of the variables.

       One  caveat:  In most Aleph formats, you cannot use ~ in a filename you
       give directly to Aleph, because ~ is an active character, and hence  is
       expanded,  not  taken as part of the filename.  Other programs, such as
       Metafont, do not have this problem.

              Normally, Aleph puts its output files in the current  directory.
              If  any  output file cannot be opened there, it tries to open it
              in  the  directory  specified  in   the   environment   variable
              TEXMFOUTPUT.   There is no default value for that variable.  For
              example, if you say tex paper and the current directory  is  not
              writable,  if  TEXMFOUTPUT has the value /tmp, Aleph attempts to
              create /tmp/paper.log (and  /tmp/paper.dvi,  if  any  output  is

              Search  path for \input and \openin files.  This should probably
              start with ``.'', so that user files  are  found  before  system
              files.   An empty path component will be replaced with the paths
              defined in the texmf.cnf file.  For example,  set  TEXINPUTS  to
              ".:/home/usr/tex:"   to   prepend   the   current  direcory  and
              ``/home/user/tex'' to the standard search path.

              Command template for switching to editor.  The default,  usually
              vi, is set when Aleph is compiled.


       This  manual  page  is  not  meant  to  be  exhaustive.   The  complete
       documentation for this version of Aleph can be found in the info manual

       This  version  of Aleph implements a number of optional extensions.  In
       fact, many of these extensions conflict to a greater or  lesser  extent
       with  the  definition  of Aleph.  When such extensions are enabled, the
       banner printed when Aleph starts is changed to print Alephk instead  of

       This version of Aleph fails to trap arithmetic overflow when dimensions
       are added or subtracted.  Cases where this occurs are rare, but when it
       does the generated DVI file will be invalid.
