"""Represents a named font.
Constructor options are:
font -- font specifier (name, system font, or (family, size, style)-tuple)
name -- name to use for this font configuration (defaults to a unique name)
exists -- does a named font by this name already exist?
Creates a new named font if False, points to the existing font if True.
Raises _tkinter.TclError if the assertion is false.
the following are ignored if font is specified:
family -- font 'family', e.g. Courier, Times, Helvetica
size -- font size in points
weight -- font thickness: NORMAL, BOLD
slant -- font slant: ROMAN, ITALIC
underline -- font underlining: false (0), true (1)
overstrike -- font strikeout: false (0), true (1)
