RedHat 9 (Linux i386) - man page for einitex (redhat section 1)

ETEX(1) 			     General Commands Manual				  ETEX(1)

NAME
       etex, einitex, evirtex - extended TeX

SYNOPSIS
       etex [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.

       e-TeX is the first concrete result of an international research & development project, the
       NTS  Project, which was established under the aegis of DANTE e.V. during 1992. The aims of
       the project are to perpetuate and  develop  the	spirit	and  philosophy  of  TeX,  whilst
       respecting Knuth's wish that TeX should remain frozen.

       e-TeX  can be used in two different modes: in compatibility mode it is supposed to be com-
       pletely interchangable with standard TeX.  In extended mode  several  new  primitives  are
       added that facilitate (among other things) bidirectional typesetting.

       An extended mode format is generated by prefixing the name of the source file for the for-
       mat with an asterisk (*).  Such formats are often prefixed with an `e', hence etex as  the
       extended  version  of tex and elatex as the extended version of latex.  However, eplain is
       an exception to this rule.

       The einitex and evirtex commands are e-TeX's analogues to the initex and virtex	commands.
       In this installation, they are symlinks to the etex executable.

       e-TeX's handling of its command-line arguments is similar to that of TeX.

OPTIONS
       This version of e-TeX understands the following command line options.

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

       --help Print help message and exit.

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

       --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.

       --mltex
	      Enable MLTeX extensions.

       --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.

       --translate-file tcxname
	      Use the tcxname translation table.

       --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 e-TeX formats, you cannot use ~ in a filename you give directly to  e-
       TeX,  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, e-TeX 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,  e-TeX  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.

       TEXFONTS
	      Search path for font metric (.tfm) files.

       TEXFORMATS
	      Search path for format files.

       TEXPOOL
	      search path for einitex internal strings.

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

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

       etex.pool
	      Encoded text of e-TeX's messages.

       texfonts.map
	      Filename mapping definitions.

       *.tfm  Metric files for e-TeX's fonts.

       *.efmt Predigested e-TeX format (.efmt) files.

BUGS
       This  version of e-TeX 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.
