# be transmitted base64-encoded and not as a raw-string.

#
|
|
# You can use XMLRPC::Base64 on the client and server-side as a
|
|
# parameter and/or return-value.

# 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.
