+     "Thr purpose of the package is to provide an alternative interface to the CM
+Sans Serif boldface fonts.  The EC (T1, Cork) encoded versions of the CM Sans
+Serif boldface extended fonts differ considerably from the traditionally (OT1)
+encoded ones: at large sizes, above 10pt, they have thinner strokes and are
+much wider.  At 25pt they are hardly to be recognized as being boldface'.
+This package attempts to make these T1 fonts look like the traditional ones
+did.  You do not need any new fonts; the package just changes the way LaTeX
+makes use of the current ones.")
