fmtutil.cnf - configuration file for fmtutil
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.
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).
