%Why do you care about this option?
%There are two answers. One is that it takes less paper to print a
%preliminary draft of the thesis. The second is that singlespacing
%makes the structural units of the document more apparent. Single
%spacing makes it easy to identify definitions, lemmas, theorems, and
%so on, and it makes apparent such problems as a paragraph that is
%running too long. On the other hand, the double spacing is good for
%checking for typographical errors in a manuscript. Note that a
%document printed in singlespacing and doublespacing formats will
%have its problems with page and line breaks in different locations.
