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 for‐
   mat.  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).
