Usage: fmtutil [OPTION]... CMD [ARG]...
Usage: mktexfmt FMT.fmt|BASE.base|MEM.mem|FMTNAME

Rebuild and manage TeX formats (and Metafont bases and MetaPost mems).

If the command name ends in mktexfmt, only one format can be created.
The only options supported are --help and --version, and the command
line must consist of either a format name, with its extension, or a
plain name that is passed as the argument to --byfmt (see below).  The
full name of the generated file (if any) is written to stdout, and
nothing else.

If not operating in mktexfmt mode, the command line can be more general,
and multiple formats can be generated, as follows.

Valid options for fmtutil:
  --cnffile FILE
  --fmtdir DIRECTORY
  --no-engine-subdir         don't use engine-specific subdir of the fmtdir
  --quiet                    (not implemented, just for compatibility)
  --test                     (not implemented, just for compatibility)
  --dolinks                  (not implemented, just for compatibility)
  --force                    (not implemented, just for compatibility)

Valid commands for fmtutil:
  --all                      recreate all format files
  --missing                  create all missing format files
  --refresh                  recreate only existing format files
  --byengine ENGINENAME      (re)create formats using ENGINENAME
  --byfmt FORMATNAME         (re)create format for FORMATNAME
  --byhyphen HYPHENFILE      (re)create formats that depend on HYPHENFILE
  --enablefmt FORMATNAME     enable formatname in config file
  --disablefmt FORMATNAME    disable formatname in config file
  --listcfg                  list (enabled and disabled) configurations,
                             filtered to available formats
  --catcfg                   output the content of the config file
  --showhyphen FORMATNAME    print name of hyphenfile for format FORMATNAME
  --edit                     edit config file
  --version                  show version info
  --help                     show this message

The config file is named fmtutil.cnf, and
running  kpsewhich fmtutil.cnf  should show the active file.
