Detailed Description
template<class T>
struct vcsn::misc::escaper< T >
IO Manipulator to escape some characters when displaying them.
It is often desirable when printing words to escape some particular characters. As an example, when printing a rational expression, the word "foo+bar" (where '+' is a letter from the alphabet) should be printed "foo\+bar".
This manipulator allow an user to do so. When used on a stream using an << operator, the argument of type T held by this manipulator is displayed as if its << operator had been called, but with some characters escaped.
By default the escaped characters are those returned by vcsn::misc::usual_escaped_characters (). You may control those characters using the vcsn::misc::setesc manipulator.
