% Definition List:  A definition list is essentially the same as a description
% list, except that there is a required argument specifying the indentation to
% be used, and the list items are left-justified in the item columns, rather
% than right-justified.

% Reference List:  A list of references is formatted with no item label, the
% first line of text flush left, and all subsequent lines in the reference
% indented a few spaces to the right (like ApJ references).
