+% MATHCODES
+%
+% The mathcodes for the letters A, ..., Z, a, ..., z are changed to
+% generate text italic font rather than math italic by default. This makes
+% multi-letter identifiers look better. The mathcode for character c
+% is set to "7000 (variable family) + "400 (text italic) + c.
+% See the TeXBook, page 154.
