+Devanagari and Latin scripts.  This font family has been created for
+use in headlines and other display-sized text on screen.  Five font
+styles make up the initial release.
+
+The Teko typeface features letterforms with low stroke contrast,
+square proportions and a structure that appears visually simple.
+
+The Regular, Medium and Semibold fonts are recommended for use in long
+headlines, while Bold is intended primarily for setting just one or
+two words.  The Light is a variant that may be put to good use in
+large headlines on websites.  At display sizes, Teko works equally
+well on screen or in print.  Each font contains 1090 glyphs, offering
+full support for the conjuncts and ligatures required by languages
+written with the Devanagari script.")
