NAME

     mmencode - Translate to and from mail-oriented encoding for-
     mats



SYNOPSIS
     mmencode [ -ubq ] [ -o outputfile ] [ inputfile ]



DESCRIPTION
     The mmencode 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(1) and
     uudecode(1) 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 inputfile to standard out-
     put.  If no inputfile is specified, then the standard  input
     is processed.

     The following options are available.

     -b   Tells mmencode to process ``base64'' encoding (which is
          the default).

     -q   Tells mmencode to process ``quoted-printable'' encoding
          instead of ``base64''.

     -u   Tells mmencode to decode the input, rather than  encode
          it.

     -o   Output will be sent to outputfile instead of the  stan-
          dard output.



RATIONALE
     mmencode is intended to be a replacement  for  uuencode  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,  uuen-
     code  does  not generally work well in a pipe, although some
     variants have been modified to do so.   mmencode  implements
     the  encodings  which  were  defined  for  MIME  as uuencode
     replacements, and should be  considerably  more  robust  for
     email use.

BUGS
     This program is derived from the mmencode  provided  in  the
     metamail  package.   That package also links this program to
     the name mimencode.  The -p option, which is provided in the
     metamail implementation, is accepted as a noop.
