=head1 NAME
MIME::Decoder::Binary - perform no encoding/decoding
=head1 SYNOPSIS
A generic decoder object; see L<MIME::Decoder> for usage.
=head1 DESCRIPTION
A MIME::Decoder subclass for the C<"binary"> encoding (in other words,
no encoding).
The C<"binary"> decoder is a special case, since it's ill-advised
to read the input line-by-line: after all, an uncompressed image file might
conceivably have loooooooooong stretches of bytes without a C<"\n"> among
them, and we don't want to risk blowing out our core. So, we
read-and-write fixed-size chunks.
Both the B<encoder> and B<decoder> do a simple pass-through of the data
from input to output.
