NAME
       luatex, texlua, texluac - An extended version of pdfTeX using Lua as an embedded scripting
       language

SYNOPSIS
       luatex [--lua=FILE] [OPTION]...	[TEXNAME[.tex]] [COMMANDS]
       luatex [--lua=FILE] [OPTION]...	\FIRST-LINE
       luatex [--lua=FILE] [OPTION]...	&FMT [ARGS]

DESCRIPTION
       Run the luaTeX typesetter on TEXNAME, usually creating TEXNAME.pdf.   Any  remaining  COM-
       MANDS are processed as luaTeX input, after TEXNAME is read.

       Alternatively,  if  the	first  non-option argument begins with a backslash, interpret all
       non-option arguments as a line of luaTeX input.

       Alternatively, if the first non-option argument begins with a &, the next word is taken as
       the FMT to read, overriding all else. Any remaining arguments are processed as above.

       If no arguments or options are specified, prompt for input.

       If called as texlua it acts as lua interpreter.	If called as texluac it acts as lua byte-
       code compiler.

       LuaTeX is an extended version of pdfTeX with Unicode and OpenType  font	support,  embeded
       Lua  scripting  language,  the  e-TeX and Omega extensions, as well as integrated MetaPost
       engine, that can create PDF files as well as DVI files.	For more information  about  lua-
       tex,  see  http://www.luatex.org,  you can read LuaTeX manual using texdoc utility (texdoc
       luatex).

       All LuaTeX text input and output is considered to be Unicode text.

       In DVI mode, luaTeX can be used as a complete replacement for the TeX engine.

       In PDF mode, luaTeX can natively handle the PDF, JPG, JBIG2,  and  PNG  graphics  formats.
       luaTeX  cannot  include	PostScript or Encapsulated PostScript (EPS) graphics files; first
       convert them to PDF using epstopdf (1).

OPTIONS
       When the LuaTeX executable starts, it looks for the --lua commandline option.  If there is
       no  --lua  option,  the	commandline is interpreted in a similar fashion as in traditional
       pdfTeX and Aleph. But if the option is present, LuaTeX will enter an alternative  mode  of
       commandline  parsing  in  comparison to the standard web2c programs. The presence of --lua
       makes most of other options unreliable, because the lua initialization  file  can  disable
       kpathsea and/or hook functions into various callbacks.

       --lua=FILE
	      The lua initialization file.

       The following two options alter the executable behaviour:

       --luaonly
	      Start  LuaTeX  as  a Lua interpreter. In this mode, it will set Lua's arg[0] to the
	      found script name, pushing preceding options in negative values and the rest of the
	      commandline in the positive values, just like the Lua interpreter. LuaTeX will exit
	      immediately after executing the specified Lua script.

       --luaconly
	      Start LuaTeX as a Lua byte compiler. In this mode, LuaTeX is exactly like luac from
	      the  standalone  Lua  distribution, except that it does not have the -l switch, and
	      that it accepts (but ignores) the --luaconly switch.

       Then the regular web2c options:

       --debug-format
	      Debug format loading.

       --draftmode
	      Sets \pdfdraftmode so luaTeX doesn't write a PDF	and  doesn't  read  any  included
	      images, thus speeding up execution.

       --enable-write18
	      Synonym for --shell-escape.

       --disable-write18
	      Synonym for --no-shell-escape.

       --shell-escape
	      Enable  the \write18{command} construct, and Lua functions os.execute(), os.exec(),
	      os.spawn(), and io.popen().  The command can be any shell command.  This	construct
	      is normally disallowed for security reasons.

       --no-shell-escape
	      Disable  the \write18{command} construct and the other Lua functions, even if it is
	      enabled in the texmf.cnf file.

       --shell-restricted
	      Enable restricted version of \write18,  os.execute(),  os.exec(),  os.spawn(),  and
	      io.popen(), only commands listed in texmf.cnf file are allowed.

       --file-line-error
	      Print  error  messages in the form file:line:error which is similar to the way many
	      compilers format them.

       --no-file-line-error
	      Disable printing error messages in the file:line:error style.

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

       --help Print help message and exit.

       --ini  Start  in  INI  mode,  which is used to dump formats.  The INI mode can be used for
	      typesetting, but no format is preloaded, and  basic  initializations  like  setting
	      catcodes may be required.

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

       --jobname=NAME
	      Use NAME for the job name, instead of deriving it from the name of the input file.

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

       --mktex=FMT
	      Enable mktexFMT generation, where FMT must be either tex or tfm.

       --nosocket
	      Disable the luasocket (network) library.

       --output-comment=STRING
	      In DVI mode, use STRING for the DVI file comment instead of the date.   This
	      option is ignored inPDF mode.

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

       --output-format=FORMAT
	      Set the output format mode, where FORMAT must be either pdf  or  dvi.   This
	      also influences the set of graphics formats understood by luaTeX.

       --progname=NAME
	      Pretend to be program NAME (only for kpathsea).

       --recorder
	      Enable  the  filename recorder.  This leaves a trace of the files opened for
	      input and output in a file with extension .fls.

       --safer
	      Disable some Lua commands that can easily be abused by a malicious document.

       --synctex=NUMBER
	      Enable/disable SyncTeX extension.

       --version
	      Print version information and exit.

       --credits
	      Print credits and version details.

       The following options are ignored:

       --8bit, --etex, --parse-first-line, --no-parse-first-line
	      These are always on.

       --default-translate-file=TCXNAME, --translate-file=TCXNAME
	      These are always off.

AUTHORS
       The primary authors of LuaTeX are Hartmut Henkel, Taco Hoekwater, and  Hans  Hagen,
       with help from Martin Schroder, Karel Skoupy, and Han The Thanh.

       TeX  was  designed  by Donald E. Knuth, who implemented it using his Web system for
       Pascal programs.  It was ported to Unix at Stanford by Howard Trickey, and at  Cor-
       nell  by  Pavel	Curtis.  The version now offered with the Unix TeX distribution is
       that generated by the Web to C system (web2c), originally written by Tomas  Rokicki
       and Tim Morgan.
