  $prg $version
  Set up embedding of Japanese/Chinese/Korean fonts via updmap.cfg.

    This script searches for some of the most common fonts
    for embedding into pdfs by dvipdfmx.

    In addition it allows to set up arbitrary font families
    to be embedded into the generated pdf files, as long
    as at least the representative map file is present.
    Other map files will be used if available:

      For Japanese:
        ptex-<family>.map (representative map file)
        uptex-<family>.map
        otf-<family>.map
        otf-up-<family>.map

      For Simplified Chinese, Traditional Chinese and Korean:
        uptex-<NN>-<family>.map (representative map file)
        otf-<NN>-<family>.map
       (NN being: sc, tc, ko)

  Please see the documentation of updmap for details (updmap --help).

  Usage:  $prg [OPTION] {<fontname>|auto|nofont|status}

     <family>    Embed an arbitrary font family <family>, at least
                 the representative map file has to be available.
     auto:       If the current status is noEmbed or unknown, try to embed
                 one of the supported font families automatically.
                 If none of them is available, fall back to nofont
     nofont:     Embed no fonts (and rely on system fonts when displaying pdfs).
                 If your system does not have any of the supported font
                 families, this target is selected automatically.
     status:     Get information about current environment and usable font maps.

  Options:
    -n, --dry-run  Do not actually run updmap
    -h, --help     Show this message and exit
    --mode=NN      Setup for Japanese (NN=ja), Korean (NN=ko),
                   Simplified Chinese (NN=sc), Traditional Chinese (NN=tc)
    --NN           Shorthand for --mode=NN
    --jis2004      Use JIS2004 variants for default fonts of (u)pTeX
    --sys          Run in sys mode, i.e., call updmap -sys
    --user         Run in user mode, i.e., call updmap -user or updmap,
                   by checking the version of the updmap script.
                   If a non-parsable output of `updmap --version' is found,
                   a new updmap with --user option is assumed.
                   If this is not the case, explicitly use --old.
    --old          Makes $prg call `updmap' without --user argument in user mode.
    --force        Set up font embedding even if the font is not available.
    --version      Show version information and exit
