-.SH NAME
-omega, iniomega, viromega \- extended unicode TeX
-.SH SYNOPSIS
-.B omega
-.RI [ options ]
-[\fB&\fR \fIformat\fR ]
-[ \fIfile\fR | \fB\e\fR \fIcommands\fR ]
-.\"=====================================================================
-.SH DESCRIPTION
-Run the Omega typesetter on
-.IR file ,
-usually creating
-.IR file.dvi .
-If the file argument has no extension, ".tex" will be appended to it. 
-Instead of a filename, a set of Omega commands can be given, the first
-of which must start with a backslash.
-With a 
-.BI & format
-argument Omega uses a different set of precompiled commands,
-contained in
-.IR format.fmt ;
-it is usually better to use the
-.B -fmt
-.I format
-option instead.
-.PP
-Omega is a version of the \*(TX program modified for multilingual
-typesetting.  It uses unicode, and has additional primitives for
-(among other things) bidirectional typesetting.
-.PP
-The
-.B iniomega
-and
-.B viromega
-commands are Omega's analogues to the
-.B initex
-and
-.B virtex
-commands.  In this installation, they are symlinks to the
-.B omega
-executable.
-.PP
-Omega's command line options are similar to those of \*(TX.
-.PP
-Omega is experimental software.
-.\"=====================================================================
-.SH OPTIONS
-This version of Omega understands the following command line options.
-.TP
-.BI --oft \ format
-.rb
-Use
-.I format
-as the name of the format to be used, instead of the name by which
-Omega was called or a
-.I %&
-line.
-.TP
-.B -halt-on-error
-.rb
-Exit with an error code when an error is encountered during processing.
-.TP
-.B --help
-.rb
-Print help message and exit.
-.TP
-.B --ini
-.rb
-Be
-.BR iniomega ,
-for dumping formats; this is implicitly true if the program is called
-as
-.BR iniomega .
-.TP
-.BI --interaction \ mode
-.rb
-Sets the interaction mode.  The mode can be one of
-.IR batchmode ,
-.IR nonstopmode ,
-.IR scrollmode ,
-and
-.IR errorstopmode .
-The meaning of these modes is the same as that of the corresponding
-\ecommands.
-.TP
-.B --ipc
-.rb
-Send DVI output to a socket as well as the usual output file.  Whether
-this option is available is the choice of the installer.
-.TP
-.B --ipc-start
-.rb
-As

-.BI --kpathsea-debug \ bitmask
-.rb
-Sets path searching debugging flags according to the bitmask.  See the
-.I Kpathsea
-manual for details.
-.TP

-.B --version
-.rb
-Print version information and exit.
-.\"=====================================================================
-.SH ENVIRONMENT
-See the Kpathsearch library documentation (the `Path specifications'
-node) for precise details of how the environment variables are used.
-The
-.B kpsewhich
-utility can be used to query the values of the variables.
-.PP
-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
-\*(MF, do not have this problem.
-.PP
-.TP
-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
-.I tex paper
-and the current directory is not writable, if TEXMFOUTPUT has
-the value
-.IR /tmp ,
-Omega attempts to create
-.I /tmp/paper.log
-(and
-.IR /tmp/paper.dvi ,
-if any output is produced.)
-.TP
-TEXINPUTS
-Search path for
-.I \einput
-and
-.I \eopenin
-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
-.I 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.
-.TP
-TEXEDIT
-Command template for switching to editor.  The default, usually
-.BR vi ,
-is set when Omega is compiled.
-.\"=====================================================================
-.SH FILES
-The location of the files mentioned below varies from system to
-system.  Use the
-.B kpsewhich
-utility to find their locations.
-.TP
-.I omega.pool
-Encoded text of Omega's messages.
-.TP
-.I *.oft
-Predigested Omega format (.\|oft) files.
-.br
-.\"=====================================================================
-.SH NOTES
-This manual page is not meant to be exhaustive.  The complete
-documentation for this version of Omega can be found in the info
-manual
-.IR "Web2C: A TeX implementation" .
-.\"=====================================================================
-.SH BUGS
-This version of Omega implements a number of optional extensions.
-In fact, many of these extensions conflict to a greater or lesser
-extent with the definition of Omega.  When such extensions are
-enabled, the banner printed when Omega starts is changed to print
-.B Omegak
-instead of
-.BR Omega .
-.PP
-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
-.I DVI
-file will be invalid.
-.PP
-The
-.I DVI
-files produced by Omega may use extensions which make them incompatible
-with most software designed to handle
-.I DVI
-files.  In order to print or preview them, you should use
-.B odvips
-to generate a PostScript file.
-.PP
-Omega is experimental software, and if you are an active user it is
-strongly recommended that you subscribe to the Omega mailing list.

-@ The \ph\ compiler with which the present version of \TeX\ was prepared has

-we can write
-$$\vbox{\halign{#\hfil\qquad&#\hfil\cr
-|reset(f,@t\\{name}@>,'/O')|&for input;\cr
-|rewrite(f,@t\\{name}@>,'/O')|&for output.\cr}}$$

-$[\langle\\{any}\rangle]$ of \\{char}}', stands for the name of
-the external file that is being opened for input or output.
-Blank spaces that might appear in \\{name} are ignored.
-
-The `\.{/O}' parameter tells the operating system not to issue its own
-error messages if something goes wrong. If a file of the specified name
-cannot be found, or if such a file cannot be opened for some other reason
-(e.g., someone may already be trying to write the same file), we will have

-In order to make efficient use of storage space, \TeX\ bases its major data
-structures on a |memory_word|, which contains either a (signed) integer,
-possibly scaled, or a (signed) |glue_ratio|, or a small number of
-fields that are one half or one quarter of the size used for storing
-integers.
-
-That is the description for \TeX.  For $\Omega$, we are going to keep
-the same terminology, except that |quarterword| is going to refer to
-16~bits, and |halfword| is going to refer to 32~bits.  So, in fact,
-a |memory_word| will take 64 bits, and, on a 64-bit machine, will run
-smaller than \TeX\ will!
-
-@z
-%---------------------------------------
-@x [8] m.110 l.2378 - Omega
-Since we are assuming 32-bit integers, a halfword must contain at least
-16 bits, and a quarterword must contain at least 8 bits.
-@^system dependencies@>
-But it doesn't hurt to have more bits; for example, with enough 36-bit
-words you might be able to have |mem_max| as large as 262142, which is
-eight times as much memory as anybody had during the first four years of
-\TeX's existence.
-
-N.B.: Valuable memory space will be dreadfully wasted unless \TeX\ is compiled
-by a \PASCAL\ that packs all of the |memory_word| variants into
-the space of a single integer. This means, for example, that |glue_ratio|
-words should be |short_real| instead of |real| on some computers. Some
-\PASCAL\ compilers will pack an integer whose subrange is `|0..255|' into
-an eight-bit field, but others insist on allocating space for an additional
-sign bit; on such systems you can get 256 values into a quarterword only
-if the subrange is `|-128..127|'.

-Note that the format of a |char_node| allows for up to 256 different
-fonts and up to 256 characters per font; but most implementations will
-probably limit the total number of fonts to fewer than 75 per job,
-and most fonts will stick to characters whose codes are
-less than 128 (since higher codes
-are more difficult to access on most keyboards).
-
-Extensions of \TeX\ intended for oriental languages will need even more
-than $256\times256$ possible characters, when we consider different sizes
-@^oriental characters@>@^Chinese characters@>@^Japanese characters@>
-and styles of type.  It is suggested that Chinese and Japanese fonts be
-handled by representing such characters in two consecutive |char_node|
-entries: The first of these has |font=font_base|, and its |link| points
-to the second;
-the second identifies the font and the character dimensions.
-The saving feature about oriental characters is that most of them have
-the same box dimensions. The |character| field of the first |char_node|
-is a ``\\{charext}'' that distinguishes between graphic symbols whose
-dimensions are identical for typesetting purposes. (See the \MF\ manual.)
-Such an extension of \TeX\ would not be difficult; further details are
-left to the reader.

-$\Omega$ is capable of reading not only \.{TFM} files, but also
-\.{OFM} files, which can describe fonts with up to 65536 characters
-and with huge lig/kern tables.  These fonts will often be virtual
-fonts built up from real fonts with 256 characters, but $\Omega$
-is not aware of this.  
-
-The documentation below describes \.{TFM} files, with slight additions
-to show where \.{OFM} files differ.

-and as few as 0 characters (if |bc=ec+1|).

-16 or more bits, the most significant bytes appear first in the file.

-The first 52 bytes (13 words) of an \.{OFM} file contains thirteen
-32-bit integers that give the lengths of the various subsequent
-portions of the file.  The first word is 0 (future versions of
-\.{OFM} files could have different values;  what is important is that
-the first two bytes be 0 to differentiate \.{TFM} and \.{OFM} files).
-The next twelve integers are as above, all nonegative and less
-than~$2^{31}$.  We must have |bc-1<=ec<=65535|, and
-$$\hbox{|lf=13+lh+2*(ec-bc+1)+nw+nh+nd+ni+nl+nk+ne+np|.}$$

 To define a new symbol (e.g., a function) to be used in the change

 TeX/MF/MP) or common.defines (otherwise) here, as well as making the

 somewhere, probably cpascal.h.  Of course no underscores are allowed,
