NAME
       MIME::Decoder::Base64 - encode/decode a "base64" stream

SYNOPSIS
       A generic decoder object; see MIME::Decoder for usage.

DESCRIPTION
       A MIME::Decoder subclass for the "base64" encoding.  The name was chosen to jibe with the
       pre-existing MIME::Base64 utility package, which this class actually uses to translate
       each chunk.

       ·   When decoding, 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).

       ·   When encoding, 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 2045 specifies:
               The encoded output stream must be represented in lines of no more
               than 76 characters each.
