!!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 version 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 unicode, and has
additional primitives for (among other things) bidirectional
typesetting.


The __iniomega__ and __viromega__ commands are Omega's
analogues to the __initex__ and __virtex__ commands.
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 mktex''fmt'', where ''fmt'' must be one of
''tex'' or ''tfm''.


__--no-maketex__ ''fmt''


Disable mktex''fmt'', 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.


__--recorder__


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.)


__--shell-escape__


Enable the __write18{__''command''__}__ construct.
The ''command'' can be any Bourne shell command. 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 M ETAFONT ,
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
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'', 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
''


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 subtracted. 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__.
