DDEESSCCRRIIPPTTIIOONN
       This  manual page is not meant to be exhaustive.  The com-
       plete documentation for this version of TeX can  be  found
       in the info file or manual _W_e_b_2_C_: _A _T_e_X _i_m_p_l_e_m_e_n_t_a_t_i_o_n.

       Omega  is a version of the TeX program modified for multi-
       lingual typesetting.  It uses unicode, and has  additional
       primitives for (among other things) bidirectional typeset-
       ting.

       The iinniioommeeggaa and vviirroommeeggaa commands are  Omega's  analogues
       to  the iinniitteexx and vviirrtteexx commands.  In this installation,
       they are symlinks to the oommeeggaa executable.

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

       Omega is experimental software.

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

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

       ----hheellpp Print help message and exit.

       ----iinnii  Be iinniioommeeggaa, for dumping formats; this  is  implic-
              itly true if the program is called as iinniioommeeggaa.

       ----iinntteerraaccttiioonn _m_o_d_e
              Sets  the interaction mode.  The mode can be one of
              _b_a_t_c_h_m_o_d_e, _n_o_n_s_t_o_p_m_o_d_e, _s_c_r_o_l_l_m_o_d_e, and  _e_r_r_o_r_s_t_o_p_-
              _m_o_d_e.   The  meaning  of these modes is the same as
              that of the corresponding \commands.

       ----iippcc  Send DVI output to a socket as well  as  the  usual
              output  file.   Whether this option is available is
              the choice of the installer.

       ----iippcc--ssttaarrtt
              As ----iippcc, and starts the server at the other end as
              well.   Whether  this  option  is  available is the
              choice of the installer.

       ----kkppaatthhsseeaa--ddeebbuugg _b_i_t_m_a_s_k
              Sets path searching debugging  flags  according  to
              the  bitmask.  See the _K_p_a_t_h_s_e_a manual for details.

       ----mmaakkeetteexx _f_m_t
              Enable mktex_f_m_t, where _f_m_t must be one  of  _t_e_x  or
              _t_f_m.

       ----nnoo--mmaakkeetteexx _f_m_t
              Disable  mktex_f_m_t,  where _f_m_t must be one of _t_e_x or
              _t_f_m.

       ----oouuttppuutt--ccoommmmeenntt _s_t_r_i_n_g
              Use _s_t_r_i_n_g for the DVI file comment instead of  the
              date.

       ----pprrooggnnaammee _n_a_m_e
              Pretend  to be program _n_a_m_e.  This affects both the
              format used and the search paths.

       ----sshheellll--eessccaappee
              Enable the \\wwrriittee1188{{_c_o_m_m_a_n_d}} construct.   The  _c_o_m_-
              _m_a_n_d  can  be  any Bourne shell command.  This con-
              struct is normally disallowed for security reasons.

       ----vveerrssiioonn
              Print version information and exit.

EENNVVIIRROONNMMEENNTT
       See the Kpathsearch library documentation (the `Path spec-
       ifications' node) for precise details of how the  environ-
       ment  variables  are  used.   The kkppsseewwhhiicchh 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 , do not have
       this problem.


       TEXMFOUTPUT
              Normally, Omega puts its output files in  the  cur-
              rent  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  _t_e_x  _p_a_p_e_r  and the current
              directory is not writable, if TEXMFOUTPUT  has  the
              value _/_t_m_p, Omega attempts to create _/_t_m_p_/_p_a_p_e_r_._l_o_g
              (and _/_t_m_p_/_p_a_p_e_r_._d_v_i, if any output is produced.)

       TEXINPUTS
              Search path for _\_i_n_p_u_t  and  _\_o_p_e_n_i_n  files.   This

              should  probably  start  with  ``.'',  so that user
              files are found before system files.

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

FFIILLEESS
       The location of the files mentioned below varies from sys-
       tem  to  system.   Use the kkppsseewwhhiicchh utility to find their
       locations.

       _o_m_e_g_a_._p_o_o_l
              Encoded text of Omega's messages.

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

BBUUGGSS
       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  _D_V_I  file
       will be invalid.

       The  _D_V_I  files produced by Omega may use extensions which
       make them incompatible with most software designed to han-
       dle  _D_V_I  files.   In  order to print or preview them, you
       should use ooddvviippss to generate a PostScript file.
