- NAME
- mmencode - Translate to and from mail-oriented encoding for-
- mats
-
- SYNOPSIS
- mmencode[-u] [-b] [-q] [-p] [file name]
-
- DESCRIPTION
- The _m_m_e_n_c_o_d_e program simply converts a byte stream into (or
- out of) one of the standard mail encoding formats defined by
- MIME, the proposed standard for internet multimedia mail
- formats. Such an encoding is necessary because binary data
- cannot be sent through the mail. The encodings understood
- by mmencode are preferable to the use of the
- uuencode/uudecode programs, for use in mail, in several
- respects that were important to the authors of MIME.
-
- By default, mmencode reads standard input, and sends a
- "base64" encoded version of the input to standard output.
-
- The (really not necessary) "-b" option tells mmencode to use
- the "base64" encoding.
-
- The "-q" option tells mmencode to use the "quoted-printable"
- encoding instead of base64.
-
- The "-u" option tells mmencode to _d_e_c_o_d_e the standard input
- rather than encode it.
-
- If a file name argument is given, input is read from that
- file rather than from standard input.
-
- RATIONALE
- _M_m_e_n_c_o_d_e is intended to be a replacement for _u_u_e_n_c_o_d_e for
- mail and news use. The reason is simple: uuencode doesn't
- work very well in a number of circumstances and ways. In
- particular, uuencode uses characters that don't translate
- well across all mail gateways (particularly ASCII <-> EBCDIC
- gateways). Also, uuencode is not standard -- there are
- several variants floating around, encoding and decoding
- things in different and incompatible ways, with no "stan-
- dard" on which to base an implementation. Finally, uuencode
- does not generally work well in a pipe, although some vari-
- ants have been modified to do so. Mmencode implements the
- encodings which were defined for MIME as uuencode replace-
- ments, and should be considerably more robust for email use.
