Module MrMime_contentEncoding.Decoder

module Decoder: sig .. end

val p_encoding : MrMime_contentEncoding.mechanism MrMime_parser.t

See RFC2045 § 6.1:

      encoding := "Content-Transfer-Encoding" ":" mechanism

      mechanism := "7bit" / "8bit" / "binary" /
                   "quoted-printable" / "base64" /
                   ietf-token / x-toke
      

These values are not case sensitive -- Base64 and BASE64 and bAsE64 are all equivalent.
