+
+This set of fonts provides a 12pt, 100dpi proportional font with many of
+the glyphs needed for Unicode text.  I call the typeface "ClearlyU" and
+it was influenced by Donald Knuth's Computer Modern.
+
+The fonts together contain 7564 glyphs at the moment.
+
+Information about this font and samples, are located at:
