-=head1 NAME
-
-Data::YAML::Reader - Parse YAML created by Data::YAML::Writer
-
-=head1 VERSION
-
-This document describes Data::YAML::Reader version 0.0.6
-
-=head1 SYNOPSIS
-
-    use Data::YAML::Reader;
-
-    my $yr = Data::YAML::Reader->new;
-    
-    # Read from an array...
-    my $from_array = $yr->read( \@some_array );
-    
-    # ...an open file handle...
-    my $from_handle = $yr->read( $some_file );
-    
-    # ...a string containing YAML...
-    my $from_string = $yr->read( $some_string );
-    
-    # ...or a closure
-    my $from_code = $yr->read( sub { return get_next_line() } );
-
-=head1 DESCRIPTION
-
-In the spirit of L<YAML::Tiny> this is a lightweight, dependency-free
-YAML reader. While C<YAML::Tiny> is designed principally for working
-with configuration files C<Data::YAML> concentrates on the transparent
-round-tripping of YAML serialized Perl data structures.
-
-The syntax accepted by C<Data::YAML::Reader> is a subset of YAML.
-Specifically it is the same subset of YAML that L<Data::YAML::Writer>
-produces. See L<Data::YAML> for more information.
-
-=head1 INTERFACE
-
-=over
-
-=item C<< new >>
-
-Creates and returns an empty C<Data::YAML::Reader> object. No options may be passed.
-
-=item C<< read( $source ) >>
-
-Read YAML and return the data structure it represents. The YAML data may be supplied by a
-
-=over
-
-=item * scalar string containing YAML source
-
-=item * the handle of an open file
-
-=item * a reference to an array of lines
-
-=item * a code reference
-
-=back
-
-In the case of a code reference a subroutine (most likely a closure)
-that returns successive lines of YAML must be supplied. Lines should
-have no trailing newline. When the YAML is exhausted the subroutine must
-return undef.
-
-Returns the data structure (specifically either a scalar, hash ref or
-array ref) that results from decoding the YAML.
-
-=item C<< get_raw >>
-
-Return the raw YAML source from the most recent C<read>.
-
-=back
-
-=head1 BUGS AND LIMITATIONS
-
-No bugs have been reported.

-Please report any bugs or feature requests to
-C<data-yaml@rt.cpan.org>, or through the web interface at
