+PREAMBLE
+The goals of the Open Font License (OFL) are to stimulate worldwide

+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.
