DESCRIPTION
       This package provides procedures to encode binary data into base64 and back.

       ::base64::encode ?-maxlen Imaxlen? ?-wrapchar wrapchar? string
	      Base64  encodes the given binary string and returns the encoded result. Inserts the
	      character wrapchar every maxlen characters of output. wrapchar defaults to newline.
	      maxlen defaults to 60.
