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. +%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% % -% Copyright 2015 R.
