PREAMBLE

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

development of collaborative font projects, to support the font creation

efforts of academic and linguistic communities, and to provide a free and

with others.

The OFL allows the licensed fonts to be used, studied, modified and

redistributed freely as long as they are not sold by themselves. The

fonts, including any derivative works, can be bundled, embedded,

redistributed and/or sold with any software provided that any reserved

names are not used by derivative works. The fonts and derivatives,

however, cannot be released under any other type of license. The

requirement for fonts to remain under this license does not apply

to any document created using the fonts or their derivatives.
