+% The microtype package provides the ability to micromanage your
+% typography. When invoked without any options it does some nice things
+% like protruding punctuation over the edge of the right margin to make
+% the margin appear smoother. Basically it makes your book look more
+% professional with very little effort. It also has a ton of options if
+% you want to micromanage even more.
