    NAME
         mimencode - Translate to  and  from  mail-oriented  encoding
         formats
    
         (Same program also installed as "mmencode".)
    
    SYNOPSIS
         mimencode[-u] [-b] [-q] [-p] [file name] [-o outputfile]
    
    DESCRIPTION
         The mimencode 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   mimencode   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, mimencode reads  standard  input,  and  sends  a
         "base64" encoded version of the input to standard output.
    
         The (really not necessary) "-b" option  tells  mimencode  to
         use the "base64" encoding.
    
         The  "-q"  option  tells  mimencode  to  use  the   "quoted-
         printable" encoding instead of base64.
    
         The "-u" option tells mimencode to decode the standard input
         rather than encode it.
    
         The "-p" option tells mimencode to  translate  decoded  CRLF
         sequences  into the local newline convention during decoding
         and to do the reverse during encoding.  This option is  only
         meaningful when  -b (base64 encoding) is in effect.
    
         If a file name argument is given, input is  read  from  that
         file rather than from standard input.
    
         The "-o" option, which must be  followed  by  a  file  name,
         sends  output to the named file rather than to standard out-
         put.
    
    RATIONALE
         Mimencode 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
         "standard" on which to  base  an  implementation.   Finally,
         uuencode  does  not  generally work well in a pipe, although
         some variants have been modified to do so.  Mimencode imple-
         ments  the encodings which were defined for MIME as uuencode
         replacements, and should be  considerably  more  robust  for
         email use.

    BUGS
         This program was originally distributed as "mmencode".  That
         name  turns  out to conflict with a program of the same name
         that is part of the Slate software  from  BBN,  but  totally
         changing  the  name to mimencode would create other problems
         (notably with portability to systems where the left half  of
         file  names  is  limited to 8 characters).  Currently, it is
         being distributed with links under BOTH names.  The programs
         in  the  distribution  that  call the program all call it as
         "mimencode", so the "mmencode" version  may  be  deleted  at
         sites  where  it  causes  a  problem.  (The source files are
         still named "mmencode" rather than "mimencode".)
