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´´, ``luatex´´), the name of the engine that is used by that  format
       (e.g., ``tex´´, ``pdftex´´, ``luatex´´), the pattern file (e.g., language.dat, language.dat.lua), and any
       arguments (e.g., tex.ini).

       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 on the options
       --showhyphen  and --byhyphen.  If the format has no way to customize hyphenation, ``-´´ should be used to
       indicate this.

       Running "fmtutil --help" will output the main documentation for using fmtutil.cnf.

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).
