 =head1 DESCRIPTION
 
 This module extends L<B::Deparse> by making it recursively replace subroutine calls encountered when deparsing.
 
-Please refer to L<B::Deparse> documentation for what to do and how to do it. Besides the constructor syntax, everything should work the same for the two modules.

-The L<B::RecDeparse> object constructor. You can specify the underlying L<B::Deparse> constructor arguments by passing a string or an array reference as the value of the C<deparse> key. The C<level> option expects an integer that specifies how many levels of recursions are allowed : C<-1> means infinite while C<0> means none and match L<B::Deparse> behaviour.
