+is uniform); this makes some layout problems rather simple.  In more recent
+times, fonts (such as Minion Pro), which offer proportionally spaced figures,
+are increasingly being used.  The package provides mechanisms whereby such
+proportional figures may still be aligned in tabular style (for example, in
+the table of contents).")
