fmtutil.cnf(5) File Formats Manual fmtutil.cnf(5)
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).
