.SH NAME
dumpfont \- dump table structures from Font::TTF::Font
.SH SYNOPSIS
.IX Header "SYNOPSIS"
.Vb 1
\&  dumpfont [\-t taglist] [\-a attach.xml] [\-v voltsource.vtp] [\-d] font.ttf
.Ve
.PP
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.
.PP
\&\f(CW\*(C`taglist\*(C'\fR is a comma\-or space\-separated list of tags specifying which tables to dump.
If \-a is supplied then \f(CW\*(C`taglist\*(C'\fR may contain \*(AqAP\*(Aq to request dump of the attachment
point structure. If \-v is supplied or the tables to dump includes the \*(AqTSIV\*(Aq table, then the
VOLT source will first be parsed then dumped. If \-t not provided, dumps all tables.
If \f(CW\*(C`taglist\*(C'\fR contain \*(Aqwoff\*(Aq then the metadata from WOFF\-formatted fonts will be dumped.
.PP
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.
.PP
By design, dumpfont silently ignores any \*(Aq PARENT\*(Aq or \*(Aq CACHE\*(Aq elements, as well as
any element whose value is a Font::TTF::Font object, in any of the data structures.
