Most users of the :mod:`fontTools` library will be using it to generate or manipulate
OpenType and TrueType fonts. (FontTools initially only supported TrueType fonts,
gaining OpenType support in version 2.0, and so uses the ``tt`` prefix to refer to
both kinds of font. Because of this we will refer to both as "TrueType fonts"

ttFont
:mod:`.ttLib` supports fonts with TrueType-flavored glyphs (i.e., with
a ``glyf`` table), with PostScript-flavored glyphs (i.e., ``CFF`` or
``CFF2`` tables), and with all of the glyph formats used for color fonts
(``CBDT``, ``COLR``, ``sbix``, and ``SVG``). Static and variable fonts
are both supported.
Command-line utilities
----------------------
:mod:`.ttLib` includes two modules that provide command-line operations:
.. toctree::
:maxdepth: 1
removeOverlaps
scaleUpem
Supporting modules
------------------
It also contains helper modules that enable lower-level
functionality. In most cases, users will not need to access these
modules directly:
.. toctree::
:maxdepth: 1
ttCollection
ttGlyphSet
macUtils
reorderGlyphs
sfnt
standardGlyphOrder

:mod:`.ttLib.ttFont` is the primary fontTools interface for
inspecting, constructing, or deconstructing TrueType and OpenType
fonts.
The :class:`fontTools.ttLib.ttFont.TTFont` class provides access to
font-level data, including font metrics, substitution and positioning
features, and metadata, through a set of :doc:`table converters
</ttLib/tables>`. A :class:`.TTFont` may be instantiated from a single
font file, or it may be a member of a
:class:`.TTCollection`. :class:`.TTFont` objects can also be
constructed from scratch.
In addition to font-wide data, :mod:`.ttLib.ttFont` provides access to
individual glyphs through the :class:`.TTFont` object's
``glyphSet[]``. This is a dict-like object that is indexed by glyph
names. Users can use the glyphSet to interact with each glyph's
contours, components, points, and glyph metrics.
These glyph objects also implement the :doc:`Pen Protocol
</pens/index>` by providing ``.draw()`` and ``.drawPoints()``
methods. See the :doc:`pens </pens/index>` package documenation
for more.
