+%% A few commands for making math fonts bold or italic
+%% according to the context of surrounding text. It is
+%% particularly useful for avoiding problems with math
+%% boldness in section titles causing unwanted boldness
+%% in e.g. the table of contents.
+%%
+%% Thanks to Viet-Trung Luu on comp.text.tex for providing
+%% the first steps to solving this problem.
