Hi--

Just noticed that Ruby has base64.rb. But Minero Aoki wrote base64.c
for TMail. I looked at them and they do basically the same exact
thing. Should we add the c lib to Ruby instead of the .rb one for
speed?

An aside, the method names in base64.rb are kind of icky:

  b64encode   decode64   decode_b   encode64

Is there a reason for such weird method names? Minero used:

  folding_encode   decode  encode

where decode has a "strict" parameter to distinguish between the two
decode types.
