def add_file(font):
    """Add a font to pyglet's search path.

    In order to load a font that is not installed on the system, you must
    call this method to tell pyglet that it exists.  You can supply
    either a filename or any file-like object.

    The font format is platform-dependent, but is typically a TrueType font
    file containing a single font face. Note that to use a font added with this method,
    you should pass the face name (not the file name) to :meth:`pyglet.font.load` or any
    other place where you normally specify a font.

    :Parameters:
        `font` : str or file
            Filename or file-like object to load fonts from.
