|

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. |
