+The Ahem font was developed by Todd Fahrner to help test writers
+develop predictable tests. The font's em square is exactly square.
+Its ascent and descent is exactly the size of the em square. This
+means that the font's extent is exactly the same as its line-height,
+meaning that it can be exactly aligned with padding, borders, margins,
+and so forth.
+
+The font's alphabetic baseline is 0.2em above its bottom, and 0.8em
+below its top. The font has an x-height of 0.8em.
+
+The font has four glyphs:
+
+  'X' U+0058 A square exactly 1em in height and width.
+
+  'p' U+0070 A rectangle exactly 0.2em high, 1em wide, and aligned so
+             that its top is flush with the baseline.
+
+  'É' U+00C9 A rectangle exactly 0.8em high, 1em wide, and aligned so
+             that its bottom is flush with the baseline.
+
+  ' ' U+0020 A transparent space exactly 1em high and wide.
+
+Most other US-ASCII characters in the font have the same glyph as X.
+
+The Ahem font belongs to the public domain as described in COPYING.
+
+Acknowledgements: The font was originally created by Todd Fahrner in
+the late 90s, and was updated by Paul Nelson in the mid 2000s. The
+changes were the introduction of x-height information to the OS/2
+table and the addition of the space and non-breaking space glyphs.
