-Base64 encoding and decoding library
-
-Base64 is a group of similar binary-to-text encoding schemes that represent
-binary data in an ASCII string format by translating it into a radix-64
-representation.  It is specified in RFC 2045.
-
-From version 2.0 upwards, the module name is called `B64` to avoid clashing
-with other libraries such as `extlib` that use the `Base64` toplevel name.
