+Another natural use of letter spacing is to even out capitals and
+small caps, whose legibility suffers with increasing markup
+length.
+The appearance of capitals can be influenced in various ways, as
+demonstrated in the illustration to the left.
+In the first row, no modification is applied and the capitals are
+placed with full kerning.
+Row number two has the kerning removed and thus the distance between
+letters increases.
+The final row, as the second, lacks kerning and adds
+20\,\letterpercent\ letter spacing.
