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: 
http://scripts.sil.org/OFL 
 
----------------------------------------------------------- 
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 OF COPYRIGHT, PATENT, 
TRADEMARK, OR OTHER RIGHT. IN NO EVENT SHALL THE COPYRIGHT HOLDER BE LIABLE FOR 
ANY CLAIM, DAMAGES OR OTHER LIABILITY, INCLUDING ANY GENERAL, SPECIAL, 
INDIRECT, INCIDENTAL, OR CONSEQUENTIAL DAMAGES, WHETHER IN AN ACTION OF 
CONTRACT, TORT OR OTHERWISE, ARISING FROM, OUT OF THE USE OR INABILITY TO USE 
THE FONT SOFTWARE OR FROM OTHER DEALINGS IN THE FONT SOFTWARE.
