=head1 NAME

BSON::Binary - Legacy BSON type wrapper for binary data (DEPRECATED)

=head1 VERSION

version v1.10.2

=head1 DESCRIPTION

This module has been deprecated as it was horribly inefficient (unpacking
binary data to individual single-byte elements of an array!) and had a
weird API that was not compatible with the existing MongoDB Binary wrapper
implementation on CPAN.

You are strongly encouraged to use L<BSON::Bytes> instead.
