NAME
    dumpfont - dump table structures from Font::TTF::Font

SYNOPSIS
      dumpfont [-t taglist] [-a attach.xml] [-v voltsource.vtp] [-d] font.ttf

    Opens the fontfile with Font::TTF::Font->open and then uses Data::Dumper
    to pretty-print the resultant data structures for one or more font
    tables to STDOUT.

    "taglist" is a comma-or space-separated list of tags specifying which
    tables to dump. If -a is supplied then "taglist" may contain 'AP' to
    request dump of the attachment point structure. If -v is supplied or the
    tables to dump includes the 'TSIV' table, then the VOLT source will
    first be parsed then dumped. If -t not provided, dumps all tables. If
    "taglist" contain 'woff' then the metadata from WOFF-formatted fonts
    will be dumped.

    Normally dumpfont minimizes output by crossreferencing previously dumped
    structures, but this can make it difficult to diff two fonts. -d
    suppresses this behavior except where needed to break reference cycles.

    By design, dumpfont silently ignores any ' PARENT' or ' CACHE' elements,
    as well as any element whose value is a Font::TTF::Font object, in any
    of the data structures.
