-# = base64.rb: methods for base64-encoding and -decoding stings
-#
-# Author:: Yukihiro Matsumoto 
-# Documentation:: Dave Thomas and Gavin Sinclair
-#
-# Until Ruby 1.8.1, these methods were defined at the top-level.  Now
-# they are in the Base64 module but included in the top-level, where
-# their usage is deprecated.
-#
-# See Base64 for documentation.
-#

-require "kconv"

-
-# The Base64 module provides for the encoding (#encode64) and decoding
-# (#decode64) of binary data using a Base64 representation.
-# 
-# The following particular features are also provided:
-# - encode into lines of a given length (#b64encode)
-# - decode the special format specified in RFC2047 for the
-#   representation of email headers (decode_b)
-#
-# == Example
-#
-# A simple encoding and decoding. 
-# 
-#     require "base64"
-#
-#     enc   = Base64.encode64('Send reinforcements')
-#                         # -> "U2VuZCByZWluZm9yY2VtZW50cw==\n" 
-#     plain = Base64.decode64(enc)
-#                         # -> "Send reinforcements"
-#
-# The purpose of using base64 to encode data is that it translates any
-# binary data into purely printable characters.  It is specified in
-# RFC 2045 (http://www.faqs.org/rfcs/rfc2045.html).
