+.\" BEGIN Keep parallel with groff.texi node "Device and Font Files".
+The
+.I groff
+font and output device description formats are slight
+extensions of those used by AT&T device-independent
+.IR troff . \" AT&T
+.
+In distinction to the AT&T implementation,
+.I groff
+lacks a binary format;
+all files are text files.
+.
+(Plan\~9
+.I troff \" Plan 9
+has also abandoned the binary format.)
+.
+The device and font description files for a device
+.I name
+are stored in a
+.IR dev name
+directory.
+.
+The device description file is called
+.IR DESC ,
+and,
+for each font supported by the device,
+a font description file is
+.RI called\~ f,
+where
+.IR f \~is
+usually an abbreviation of a font's name and/or style.
+.
+For example,
+the
+.B ps
+(PostScript)
+device has
+.I groff
+font description files for Times roman
+.RB ( TR )
+and Zapf Chancery Medium italic
+.RB ( ZCMI ),
+among many others,
+while the
+.B utf8
+device
+(for terminal emulators)
+has only font descriptions for the roman,
+italic,
+bold,
+and bold-italic styles
+.RB ( R ,
+.BR I ,
+.BR B ,
+and
+.BR BI ,
+respectively).
+.
+.
+.P
+Device and font description files are read by the formatter,
+.IR \%troff ,
+and by output drivers.
+.
+The programs typically delegate these files' processing to an internal
+library,
+.IR libgroff ,
+ensuring their consistent interpretation.

+(2) the

+(if at all).
+.
+If a directive name is repeated,
+later entries in the file override previous ones
+(except that the paper dimensions are computed based on the
+.B res

+.\" ====================================================================
+.SH "Font description file format"
+.\" ====================================================================
+.
+On typesetting output devices,
+each font is typically available at multiple sizes.
+.
+While paper measurements in the device description file are in absolute
+units,
+measurements applicable to fonts must be proportional to the type size.
+.
+.I groff
+achieves this using the precedent set by AT&T device-independent
+.IR troff : \" AT&T
+one font size is chosen as a norm,
+and all others are scaled linearly relative to that basis.
+.
+The \[lq]unit width\[rq] is the number of basic units per point when the
+font is rendered at this nominal size.
+.
+.
+.P
+For instance,
+.IR groff 's
+.B lbp
+device uses a
+.B unitwidth
+of\~800.
+.
+Its Times roman font
+.RB (\[lq] TR \[rq])
+has a
+.B spacewidth
+of\~833;
+this is also the width of its comma,
+period,
+centered period,
+and mathematical asterisk,
+while its \[lq]M\[rq] is 2,963 basic units.
+.
+Thus,
+an \[lq]M\[rq] on the
+.B lbp
+device is 2,963 basic units wide at a notional type size of 800\~points.
+.
+(800-point type is not practical for most purposes,
+but using it enables the quantities in the font description files to be
+expressed as integers.)
+.
+.
+.P
+A font description file has two sections.
+.
+The first is a sequence of directives,
+and is parsed similarly to the
+.I DESC
+file described above.
+.
+Except for the directive names that begin the second section,
+their ordering is immaterial.
+.
+Later directives of the same name override earlier ones,
+spaces and tabs are handled in the same way,
+and the same comment syntax is supported.
+.
+Empty lines are ignored throughout.
+.
+.
+.TP
+.BI name\~ F
+The name of the font
+.RI is\~ F .
+.
+.RB \[lq] DESC \[rq]
+is an invalid font name.
+.
+Simple integers are valid,
+but their use is discouraged.
+.
+.RI ( groff
+requests and escape sequences interpret non-negative font names as
+mounting positions instead.
+.
+Further,
+a font named
+.RB \[lq] 0 \[rq]
+cannot be automatically mounted by the
+.B fonts
+directive of a
+.I DESC
+file.)
+.
+.
+.TP
+.BI spacewidth\~  n
+The width of an unadjusted inter-word space is
+.IR n \~basic
+units.
+.
+.
+.P
+The directives above must appear in the first section;
+those below are optional.
+.
+.
+.TP
+.BI slant\~ n
+The font's glyphs have a slant of
+.IR n \~degrees;
+a positive
+.I n
+slants in the direction of text flow.
+.
+.

+.BI ligatures\~ lig1\~\c
+.RI .\|.\|.\&\~ lign\~\c

+possible ligatures are
+.BR ff ,
+.BR fi ,
+.BR fl ,
+.BR ffi ,

+.BR ffl .
+.
+For compatibility with other
+.I troff
+implementations,
+the list of ligatures may be terminated with
+.RB a\~ 0 .
+.
+The list of ligatures must not extend over more than one line.
+.
+.
+.TP
+.B special
+The font is
+.IR special :
+when a glyph is requested that is not present in the current font,
+it is sought in any mounted fonts that bear this property.
+.
+.
+.P
+Other directives in this section are ignored by
+.IR \%troff ,
+but may be used by postprocessors to obtain further information about
+the font.
+.
+.
+.P
+The second section contains one or two subsections.
+.
+These can appear in either order;
+the first one encountered commences the second section.
+.
+Each starts with a directive on a line by itself.
+.
+A
+.B charset
+subsection is mandatory unless the associated
+.I DESC
+file contains the
+.B unicode
+directive.
+.
+Another subsection,
+.BR \%kernpairs ,
+is optional.
+.
+.
+.P
+The directive
+.B charset
+starts the character set subsection.
+.
+(For typesetter devices,
+this directive is misnamed since it starts a list of glyphs,
+not characters.)
+.
+It precedes a series of glyph descriptions,
+one per line.
+.
+Each such glyph description comprises a set of fields separated by
+spaces or tabs and organized as follows.
+.
+.
+.IP
+.I name metrics type code
+.RI [ entity-name ]

+.
+.P
+The
+.I width
+subfield gives the width of the glyph.
+.
+The
+.I height
+subfield gives the height of the glyph
+(upwards is positive);
+if a glyph does not extend above the baseline,
+it should be given a zero height,
+rather than a negative height.

+subfield gives the depth of the glyph,

+it should be given a zero depth,
+rather than a negative depth.

+.
+.
+.P
+For fonts used with typesetting devices,
+the
+.I type
+field gives a featural description of the glyph:
+it is a bit mask recording whether the glyph is an ascender,
+descender,
+both,
+or neither.
+.
+When a
+.B \[rs]w
+escape sequence is interpolated,
+these values are bitwise or-ed together
