fmtutil - manage TeX formats and Metafont bases, per-user

       fmtutil version r68962 (2023-11-25 00:01:43 +0100)

       Rebuild  and  manage TeX fmts and Metafont bases, collectively called "formats" here. (MetaPost no longer
       uses the past-equivalent "mems".)

       If not operating in mktexfmt mode, exactly one command must be given, filename suffixes should  generally
       not be specified, no non-option arguments are allowed, and multiple formats can be generated.

       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 be either a format name, with 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.  The system directories are used if they are writable, else the user
       directories.

       By default, the return status is zero if all formats requested are successfully built, else nonzero.

              This script runs TeX and Metafont to generate the fmt/base file, and thus all  normal  environment
              variables and search path rules for TeX/MF apply.
