<P>MIME::Decoder::Base64 - encode/decode a "base64" stream
<P><HR>
<A NAME="SYNOPSIS"><H2><A HREF="#__TOP__"><IMG SRC="icons/h1bullet.gif" ALT="Top" BORDER="0"></A> SYNOPSIS</H2></A>
<P>A generic decoder object; see <A HREF="../../MIME/Decoder.pm.html">MIME::Decoder</A> for usage.
<P><HR>
<A NAME="DESCRIPTION"><H2><A HREF="#__TOP__"><IMG SRC="icons/h1bullet.gif" ALT="Top" BORDER="0"></A> DESCRIPTION</H2></A>
<P>A <A HREF="../../MIME/Decoder.pm.html">MIME::Decoder</A> subclass for the <CODE>"base64"</CODE> encoding.
The name was chosen to jibe with the pre-existing MIME::Base64
utility package, which this class actually uses to translate each chunk.
<UL>
<P><LI>
<P>When <B>decoding</B>, the input is read one line at a time.
The input accumulates in an internal buffer, which is decoded in
multiple-of-4-sized chunks (plus a possible "leftover" input chunk,
of course).
<P><LI>
<P>When <B>encoding</B>, the input is read 45 bytes at a time: this ensures
that the output lines are not too long. We chose 45 since it is
a multiple of 3 and produces lines under 76 characters, as RFC-1521
specifies.
