+ * 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
