-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.
