NAME
       fmtutil.cnf - configuration file for fmtutil


DESCRIPTION
       The  fmtutil.cnf  file  contains  the configuration information for fmtutil(8).  Each line
       contains the name of the format (e.g., ``tex´´, ``latex´´, ``omega´´),  the  name  of  the
       engine  that is used by that format (e.g., ``tex´´, ``etex´´, ``omega´´), the pattern file
       (e.g., language.dat, language.def), and any arguments (name of an .ini file).

       Fields are separated by whitespace and complete lines can be  commented  out  with  ``#´´.
       The ``pattern file´´ field cannot be used to define a file that is used while building the
       format.  It tells fmtutil which files (separated by commas) the format creation  procedure
       reads  and it has an effect to the options --showhyphen and --byhyphen.  If the format has
       no way to customize hyphenation, a ``-´´ can be used to indicate this.


NOTES
       The tex(1) and amstex(1) formats always load hyphen.tex.  No customization  by  a  pattern
       file  is  available  for  these formats. Therefore, the pattern-file field for the tex and
       amstex is usually indicated to be empty (``-´´).

       You can, however, build customized formats on top of plain tex(1) or  amstex(1)  by  using
       bplain.tex instead of plain.tex (b for the Babel system). See, for example, the bplain.ini
       file for the bplain format).

       etex(1) loads language.def, not language.dat.

       Symbolic links to the  correct  engines  (e.g.,  bplain  ->  tex)  are  generated  by  the
       texlinks(8)  script.    Remember to run texlinks(8) if you run fmtutil(8) yourself, rather
       than using the FORMATS option in texconfig(8).
