SIL OPEN FONT LICENSE Version 1.1 - 26 February 2007

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 open framework in which
fonts may be shared and improved in partnership 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.

this license and clearly marked as such. This may include source files, build

statement(s).

"Original Version" refers to the collection of Font Software components as
distributed by the Copyright Holder(s).
