+
+    This class merges multiple files into a single OpenType font, taking into
+    account complexities such as OpenType layout (``GSUB``/``GPOS``) tables and
+    cross-font metrics (for example ``hhea.ascent`` is set to the maximum value
+    across all the fonts).
+
+    If multiple glyphs map to the same Unicode value, and the glyphs are considered
+    sufficiently different (that is, they differ in any of paths, widths, or
+    height), then subsequent glyphs are renamed and a lookup in the ``locl``
+    feature will be created to disambiguate them. For example, if the arguments
+    are an Arabic font and a Latin font and both contain a set of parentheses,
+    the Latin glyphs will be renamed to ``parenleft.1`` and ``parenright.1``,
+    and a lookup will be inserted into the to ``locl`` feature (creating it if
+    necessary) under the ``latn`` script to substitute ``parenleft`` with
+    ``parenleft.1`` etc.
+
+    Restrictions:
+
+    - All fonts must have the same units per em.
+    - If duplicate glyph disambiguation takes place as described above then the
+      fonts must have a ``GSUB`` table.
