		"""The constructor can be called with a few different arguments.
		When reading a font from disk, 'file' should be either a pathname
		pointing to a file, or a readable file object.

		It we're running on a Macintosh, 'res_name_or_index' maybe an sfnt
		resource name or an sfnt resource index number or zero. The latter
		case will cause TTLib to autodetect whether the file is a flat file
		or a suitcase. (If it's a suitcase, only the first 'sfnt' resource
		will be read!)

		The 'checkChecksums' argument is used to specify how sfnt
		checksums are treated upon reading a file from disk:
			0: don't check (default)
			1: check, print warnings if a wrong checksum is found
			2: check, raise an exception if a wrong checksum is found.

		The TTFont constructor can also be called without a 'file'
		argument: this is the way to create a new empty font.
		In this case you can optionally supply the 'sfntVersion' argument,
		and a 'flavor' which can be None, 'woff', or 'woff2'.

		If the recalcBBoxes argument is false, a number of things will *not*
		be recalculated upon save/compile:
			1) 'glyf' glyph bounding boxes
			2) 'CFF ' font bounding box
			3) 'head' font bounding box
			4) 'hhea' min/max values
			5) 'vhea' min/max values
		(1) is needed for certain kinds of CJK fonts (ask Werner Lemberg ;-).
		Additionally, upon importing an TTX file, this option cause glyphs
		to be compiled right away. This should reduce memory consumption
		greatly, and therefore should have some impact on the time needed
		to parse/compile large fonts.

		If the recalcTimestamp argument is false, the modified timestamp in the
		'head' table will *not* be recalculated upon save/compile.

		If the allowVID argument is set to true, then virtual GID's are
		supported. Asking for a glyph ID with a glyph name or GID that is not in
		the font will return a virtual GID.   This is valid for GSUB and cmap
		tables. For SING glyphlets, the cmap table is used to specify Unicode
		values for virtual GI's used in GSUB/GPOS rules. If the gid N is requested
		and does not exist in the font, or the glyphname has the form glyphN
		and does not exist in the font, then N is used as the virtual GID.
		Else, the first virtual GID is assigned as 0x1000 -1; for subsequent new
		virtual GIDs, the next is one less than the previous.

		If ignoreDecompileErrors is set to True, exceptions raised in
		individual tables during decompilation will be ignored, falling
		back to the DefaultTable implementation, which simply keeps the
		binary data.

		If lazy is set to True, many data structures are loaded lazily, upon
		access only.  If it is set to False, many data structures are loaded
		immediately.  The default is lazy=None which is somewhere in between.
