  54  =head1 NAME
  55  
  56  PerlIO::via::QuotedPrint - PerlIO layer for quoted-printable strings
  57  
  58  =head1 SYNOPSIS
  59  
  60   use PerlIO::via::QuotedPrint;
  61  
  62   open( my $in,'<:via(QuotedPrint)','file.qp' )
  63    or die "Can't open file.qp for reading: $!\n";
  64   
  65   open( my $out,'>:via(QuotedPrint)','file.qp' )
  66    or die "Can't open file.qp for writing: $!\n";
  67  
  68  =head1 DESCRIPTION
  69  
  70  This module implements a PerlIO layer that works on files encoded in the
  71  quoted-printable format.  It will decode from quoted-printable while reading
  72  from a handle, and it will encode as quoted-printable while writing to a handle.
