+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.

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.

+## Weather Icons 
+The SIL Open Font License (OFL) is a free, libre and open source license specifically designed for fonts and related software based on our experience in font design and linguistic software engineering.
+
+The OFL provides a legal framework and infrastructure for worldwide development, sharing and improvement of fonts and related software in a collaborative manner. It enables font authors to release their work under a common license that allows use, bundling, modification and redistribution. It encourages shared value, is not limited to any specific computing platform or environment, and can be used by other organizations or individuals.
+
+The OFL meets the specific needs of typographic design and engineering as well as the gold standards of the FLOSS (Free/Libre and Open Source Software) community, namely the cultural values and guidelines from the FSF 1, the Debian Free Software Guidelines2, as well as the Open Source Definition3. It draws inspiration from concepts and elements found in other licenses, but our improvements in the specific area of fonts have made the licensing model work better than other approaches currently in use.
+
+ SIL International serves language communities worldwide, building their capacity for sustainable language development, by means of research, translation, training and materials development. We have been thinking about more open and participative models for a while, for example through our partnerships with UNESCO (Initiative B@bel) and our work on the Gentium typeface. See  www.sil.org/resources/software_fonts for a detailed list of free/libre and open source software resources provided by SIL.
+
+We want to:
+
+enable others to participate in our projects
+enable others to cater to needs for which we don't have the resources
+share our wealth of knowledge and experience in the area of writing systems and pass on our tools
+equip the community to meet its font needs
+We serve the peoples of the world without regard to their material wealth, so we are grateful to those that do fund our work. Please visit  Donate to SIL International for information on supporting our efforts.
