Section mail - Debian Package: mimedecode

 This program performs the decoding of transfer encoded text type
 mime messages.  The message in its entirety is read from stdin.
 The decoded message is written to stdout; hence, this program
 behaves as a filter which may be placed wherever convenient.
 .
 It is assumed that the message has reached its point of final
 delivery and at that point 8-bit text types can be handled
 natively.  Hence, the need for transfer-encodings is not present
 any more.
 .
 Only some cases are handled:
  - encoded header fields are decoded from QP or B encoding.
  - The charset is assumed to be iso-8859-1
  - part or subparts of content-type text only are decoded
  - all other content-types are passed transparently.
