PREAMBLE
14+
The goals of the Open Font License (OFL) are to stimulate worldwide

open framework in which fonts may be shared and improved in partnership
18+
with others.
19+
20+
The OFL allows the licensed fonts to be used, studied, modified and

fonts, including any derivative works, can be bundled, embedded,
23+
redistributed and/or sold with any software provided that any reserved
