It will decode from quoted-printable while reading +from a handle, and it will encode as quoted-printable while writing to a handle. + +=head1 REQUIRED MODULES + + MIME::QuotedPrint (any) + +=head1 SEE ALSO + +L<PerlIO::via>, L<MIME::QuotedPrint>, L<PerlIO::via::Base64>, +L<PerlIO::via::MD5>, L<PerlIO::via::StripHTML>, L<PerlIO::via::Rotate>. + +=head1 ACKNOWLEDGEMENTS + +Based on example that was initially added to MIME::QuotedPrint.pm for the +5.8.0 distribution of Perl. + +=head1 COPYRIGHT + +Copyright (c) 2002-2003 Elizabeth Mattijsen.
