NAME
mimencode - translate mail-oriented encoding formats
SYNOPSIS
mimencode [-u] [-b] [-q] [-p] [filename]
DESCRIPTION
The mimencode program is a format translator that 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.
By default, mimencode reads from the standard input and sends a
base64-encoded version of the input to standard output.
Options
mimencode uses the following command line options:
-b tells mimencode to use "base64" encoding (not
necessary to specify since this is the default).
-q tells mimencode to use the "quoted-printable"
encoding instead of base64.
-u tells mimencode to decode standard input rather than
encode it.
-p 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.
filename when given, tells mimencode to read input from the
named file rather than from standard input.
USAGE
MIME encoding is used because binary data cannot be sent through the
mail. The encodings understood by mimencode may be preferable to the
use of the uuencode/uudecode programs.
mimencode is intended to be a replacement for uuencode for mail and
news use, primarily because 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 encoding and decoding in different and incompatible ways and
with no standard on which to base an implementation). Additionally,
uuencode does not always work well in a pipe, although some variants
have been modified to do so.
mimencode implements the encodings which were defined for MIME as
uuencode replacements and is expected to be more robust for email
use.
