+ This Font Software is licensed under the SIL Open Font License, Version 1.1.
+ This license is copied below, and is also available with a FAQ at:

+ -----------------------------------------------------------
+ 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.
+ .
+ DEFINITIONS
+ "Font Software" refers to the set of files released by the Copyright
+ Holder(s) under this license and clearly marked as such. This may
+ include source files, build scripts and documentation.
+ .
+ "Reserved Font Name" refers to any names specified as such after the
+ copyright statement(s).
+ .
+ "Original Version" refers to the collection of Font Software components as
+ distributed by the Copyright Holder(s).
+ .
+ "Modified Version" refers to any derivative made by adding to, deleting,
+ or substituting -- in part or in whole -- any of the components of the
+ Original Version, by changing formats or by porting the Font Software to a
+ new environment.
+ .
+ "Author" refers to any designer, engineer, programmer, technical
+ writer or other person who contributed to the Font Software.
+ .
+ PERMISSION & CONDITIONS
+ Permission is hereby granted, free of charge, to any person obtaining
+ a copy of the Font Software, to use, study, copy, merge, embed, modify,
+ redistribute, and sell modified and unmodified copies of the Font
+ Software, subject to the following conditions:
+ .
+ 1) Neither the Font Software nor any of its individual components,
+ in Original or Modified Versions, may be sold by itself.
+ .
+ 2) Original or Modified Versions of the Font Software may be bundled,
+ redistributed and/or sold with any software, provided that each copy
+ contains the above copyright notice and this license. These can be
+ included either as stand-alone text files, human-readable headers or
+ in the appropriate machine-readable metadata fields within text or
+ binary files as long as those fields can be easily viewed by the user.
+ .
+ 3) No Modified Version of the Font Software may use the Reserved Font
+ Name(s) unless explicit written permission is granted by the corresponding
+ Copyright Holder. This restriction only applies to the primary font name as
+ presented to the users.
+ .
+ 4) The name(s) of the Copyright Holder(s) or the Author(s) of the Font
+ Software shall not be used to promote, endorse or advertise any
+ Modified Version, except to acknowledge the contribution(s) of the
+ Copyright Holder(s) and the Author(s) or with their explicit written
+ permission.
+ .
+ 5) The Font Software, modified or unmodified, in part or in whole,
+ must be distributed entirely under this license, and must not be
+ distributed under any other license. The requirement for fonts to
+ remain under this license does not apply to any document created
+ using the Font Software.
+ .
+ TERMINATION
+ This license becomes null and void if any of the above conditions are
+ not met.
+ .
+ DISCLAIMER
+ THE FONT SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND,
+ EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY WARRANTIES OF
+ MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT
