# You can use XMLRPC::Base64 on the client and server-side as a
# parameter and/or return-value.
class Base64
# Creates a new XMLRPC::Base64 instance with string +str+ as the
# internal string. When +state+ is +:dec+ it assumes that the
# string +str+ is not in base64 format (perhaps already decoded),
# otherwise if +state+ is +:enc+ it decodes +str+
# and stores it as the internal string.
