+.TH FONTTOSFNT 1 __vendorversion__
+.SH NAME
+fonttosfnt \- Wrap a bitmap font in a sfnt (TrueType) wrapper
+.SH SYNOPSIS
+.B fonttosfnt
+[
+.I options
+]
+.B \-o
+.I file.ttf
+[
+.B \-\-
+]
+.IR font ...
+.SH DESCRIPTION
+Wrap a bitmap font or a set of bitmap fonts in a sfnt (TrueType or
+OpenType) wrapper.
+.SH OPTIONS
+.TP
+.B \-v
+Be verbose.
+.TP
+.B \-c
+Do not crop glyphs. This usually increases file size, but may
+sometimes yield a modest decrease in file size for small character
+cell fonts (terminal fonts).
+.TP
+.B \-b
+Write byte-aligned glyph data. By default, bit-aligned data is
+written, which yields a smaller file size.
+.TP
+.B \-r
+Do not reencode fonts. By default, fonts are reencoded to Unicode
+whenever possible.
+.TP
+.BI \-g " n"
+Set the type of scalable glyphs that we write. If
+.I n
+is 0, no scalable glyphs are written; this is legal but confuses
+most current software. If
+.I n
+is 1, a single scalable glyph (the undefined glyph) is written; this
+is recommended, but triggers a bug in current versions of
+.BR FreeType .
+If
+.I n
+is 2 (the default), a sufficiently high number of blank glyphs are
+written, which works with
+.B FreeType
+but increases file size.
+.TP
+.BI \-m " n"
+Set the type of scalable metrics that we write. If
+.I n
+is 0, no scalable metrics are written, which may or may not be legal.
+If
+.I n
+is 1, full metrics for a single glyph are written, and only left
+sidebearing values are written for the other glyphs. If
+.I n
+is 2, scalable metrics for all glyphs are written, which increases
+file size and is not recommended. The default is 1.
+.TP
+.B \-\-
+End of options.
+.SH BUGS
+Some of the font-level values, notably sub- and superscript positions,
+are dummy values.
+.SH SEE ALSO
+X(7), Xserver(1), Xft(3x).
+.I Fonts in XFree86.
+.SH AUTHOR
+.B Fonttosfnt
+was written by Juliusz Chroboczek <jch@xfree86.org> for the XFree86
+project.
