OMEGA(1)			     General Commands Manual				 OMEGA(1)

NAME
       omega, iniomega, viromega - extended unicode TeX

SYNOPSIS
       omega [options] [commands]

DESCRIPTION
       This  manual page is not meant to be exhaustive.  The complete documentation for this ver-
       sion of TeX can be found in the info file or manual Web2C: A TeX implementation.

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

       The  iniomega  and  viromega  commands are Omega's analogues to the initex and virtex com-
       mands.  In this installation, they are symlinks to the omega executable.

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

       Omega is experimental software.

OPTIONS
       This version of Omega understands the following command line options.

       --fmt format
	      Use format as the name of the format to be used, instead of the name by which Omega
	      was called or a %& line.

       --help Print help message and exit.

       --ini  Be  iniomega, for dumping formats; this is implicitly true if the program is called
	      as iniomega.

       --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.

       --ipc-start
	      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.

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

       --shell-escape
	      Enable the \write18{command} construct.  The command can be any Bourne  shell  com-
	      mand.  This construct is normally disallowed for security reasons.

       --version
	      Print version information and exit.

ENVIRONMENT
       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  Omega formats, you cannot use ~ in a filename you give directly to
       Omega, 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.

       TEXMFOUTPUT
	      Normally, Omega 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 envi-
	      ronment  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  TEXM-
	      FOUTPUT	has  the  value  /tmp,	Omega  attempts  to  create  /tmp/paper.log  (and
	      /tmp/paper.dvi, if any output is produced.)

       TEXINPUTS
	      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.

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

FILES
       The location of the files mentioned below varies from system to system.	Use the kpsewhich
       utility to find their locations.

       omega.pool
	      Encoded text of Omega's messages.

       *.fmt  Predigested Omega format (.fmt) files.

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

       The DVI files produced by Omega may use extensions which make them incompatible with  most
       software  designed to handle DVI files.	In order to print or preview them, you should use
       odvips to generate a PostScript file.

       Omega is experimental software.	If you use  it,  subscribe  to	the  omega  mailing  list
       omega@ens.fr by sending a message containing subscribe omega Your Name to listserv@ens.fr.
