+% This package provides cm old-style arrows with smaller arrowheads,
+% associated with ordinary LaTeX commands. It can be used in a document
+% that contains other amssymb arrow characters, like \twoheadrightarrow,
+% which also have small arrowheads. The options `new' and `old' allow the
+% user to use the usual new-style cm arrows together with the old-style
+% ones. The option `new' allows you to maintain the old-style by default
+% and get the old-style by putting \var before every command; conversely,
+% the option `old' allows you to maintain the new-style by default and get
+% the old-style by putting \var before every command.
