font data.  It includes the following commands:
@table @command
@item buildcff2vf
Assemble a CFF2 variable font from a .designspace file.
@item buildmasterotfs
Build master source OpenType/CFF fonts from a @file{.designspace} file
and UFO master source fonts.
@item charplot
@itemx digiplot
@itemx fontplot
@itemx fontsetplot
@itemx hintplot
@itemx waterfallplot
Aliases for the corresponding options of the @command{proofpdf} command.
@item checkoutlinesufo
Perform outline quality checks.  It can also remove path overlaps.
@item comparefamily
Look in a specific directory, examine and report on all the OpenType fonts found.
@item type1
@itemx detype1
Compile and decompile, respectively, a Type 1 font to and from a plain-text
representation.
@item makeinstancesufo
Generate UFO font instances from a set of master UFO fonts.
@item makeotfexe
Read all the font data and build the final OpenType font.
@item makeotf
This command can be used to prepare the input files needed by
@command{makeotfexe}.
@item mergefonts
Merge one or more fonts into a parent font.
@item otc2otf
Extract all OpenType fonts from the parent OpenType Collection font.
@item otf2otc
Build an OpenType Collection font file from two or more OpenType font
files.
@item otf2ttf
Converts OpenType-CFF fonts to TrueType.
@item rotatefont
Apply a Postscript transform matrix to the source font files.
@item sfntdiff
Low-level comparison of two OpenType font files.
@item sfntedit
Support table-editing, listing, and checksumming options on
sfnt-formatted files such as OpenType Format (OTF) or TrueType.
@item spot
Dump sfnt data from plain files or Macintosh resource files.
@item ttfcomponentizer
Take in a TrueType font and look for a UFO font stored in the same directory.
Use the UFO's components data to compose matching TrueType glyphs.
@item ttfdecomponentizer
Take in a TrueType font and decompose any composite glyphs into simple glyphs.
@item ttxn
Make a normalized dump of the font, or of selected tables.
@item tx
The @command{tx} (Type eXchange) is a test harness for the CoreType libraries
but also provides many useful font conversion and analysis facilities.

    "T1lib is a library for generating/rasterising bitmaps from Type 1 fonts.
It is based on the code of the X11 rasteriser of the X11 project.

The bitmaps created by t1lib are returned in a data structure with type
GLYPH.  This special GLYPH-type is also used in the X11 window system to
describe character bitmaps.  It contains the bitmap data as well as some
metric information.  But t1lib is in itself entirely independent of the
X11-system or any other graphical user interface.")

    (description
     "TECkit is a low-level toolkit intended to be used by other applications
that need to perform encoding conversions (e.g., when importing legacy data
into a Unicode-based application).  The primary component of the TECkit
package is therefore a library that performs conversions; this is the
\"TECkit engine\".  The engine relies on mapping tables in a specific binary
format (for which documentation is available); there is a compiler that
creates such tables from a human-readable mapping description (a simple
text file).

To facilitate the development and testing of mapping tables for TECkit,
several applications are also included in the current package; these
include simple tools for applying conversions to plain-text and Standard
Format files, as well as both command-line and simple GUI versions of the
TECkit compiler.  However, it is not intended that these tools will be the
primary means by which end users perform conversions, and they have not
been designed, tested, and debugged to the extent that general-purpose
applications should be.")

    (description
     "@code{fcft} is a small font loading and glyph rasterization library
built on-top of FontConfig, FreeType2 and pixman.

It can load and cache fonts from a fontconfig-formatted name string, e.g.
@code{Monospace:size=12}, optionally with user configured fallback fonts.

After a font has been loaded, you can rasterize glyphs.  When doing so, the
primary font is first considered.  If it does not have the requested glyph,
the user configured fallback fonts (if any) are considered.  If none of the
user configured fallback fonts has the requested glyph, the FontConfig
generated list of fallback fonts are checked.")
