NAME
       reformime - MIME E-mail reformatting tool

SYNOPSIS
       reformime [options...]

DESCRIPTION
       reformime is a utility for reformatting MIME messages.

       Generally, reformime expects to see an RFC 2045[1] compliant message on
       standard input, except in few cases such as the -m option.

       If no options are given, reformime prints the MIME structure of the
       message. The output consists of so-called "MIME reference tags", one
       per line. For example:

           1
           1.1
           1.2

       This shows that the message contains two different MIME sections. The
       first line of the MIME structure output will always contain "1", which
       refers to the entire message. In this case it happens to be a
       multipart/mixed message. "1.1" refers to the first section of the
       multipart message, which happens to be a text/plain section. "1.2"
       refers to the second section of the message, which happens to be an
       application/octet-stream section.

       If the message is not a MIME message, or it does not contain any
       attachments, reformime prints only "1", that refers to the entire
       message itself:

           1

       Here's the output from reformime when the first part of the message was
       itself a multipart/alternative section:

           1
           1.1
           1.1.1
           1.1.2
           1.2

       Arbitrarily complex MIME constructs are possible.

OPTIONS
       -d
           Parse a delivery status notification MIME message (RFC 1894[2]).
           reformime expects to see on standard input a MIME message that
           consists of a delivery status notification, as defined by RFC 1894.
           reformime reads the message and prints on standard output a list of
           addresses and their corresponding delivery status, as specified in
           the delivery status notification. Each line printed by reformime
           consists of a delivery status, a space, and the address.  reformime
           then terminates with a 0 exit status.  reformime produces no output
           and terminates with an exit status of 1 if the standard input does
           not contain a delivery status notification.

       -D
           Like the -d except that reformime lists the address found in the
           Original-Recipient: header, if it exists.

       -e
           Extract the contents of the indicated MIME section, and display it
           on standard output. The -s option is required when -e is specified.
           If the specified section or sections use either the base64 or
           quoted-printable encoding method, reformime automatically decodes
           it. In this case you're better off redirecting the standard output
           into a file.

       -i
           Display MIME information for each section.  reformime displays the
           contents of the Content-Type: header, any encoding used, and the
           character set.  reformime also displays the byte offset in the
           message where each section starts and ends (and where the actual
           contents of the section start, after skipping all the headers).

       -m
           Create a multipart/digest MIME message digest.

       -r
           Rewrite message, adding or standardizing RFC 2045[1] MIME headers.

       -r7
           Like -r but also convert 8bit-encoded MIME sections to
           quoted-printable.

       -r8
           Like -r but also convert quoted-printable-encoded MIME sections to
           8bit.

       -s section
           Display MIME information for this section only.  section is a MIME
           specification tag. The -s option is required if -e is also
           specified, and is optional with -i.

           Multiple sections may be specified by separating them with commas.
           reformime processes each section using the other options that were
           specified.

       -x
           Extract the contents of the indicated MIME section to a file.

       -X
           Pipe the contents of the indicated MIME section to a program.

   Extracting RFC 2045 MIME section(s) to file(s)
       The -x and -X options extract a specific MIME section to a file or to a
       pipe to an external program. Use the -s option to identify the MIME
       section to extract. If the -s option is not specified, every MIME
       section in the message is extracted, one at a time. If -s lists
       multiple sections, each section gets extracted separately.
       quoted-printable and base64 encoding are automatically decoded.

       -x
           Interactive extraction.  reformime prints the MIME content type of
           each section. Answer with 'y' or 'Y' to extract the MIME section.
           Specify the filename at the next prompt.  reformime prompts with a
           default filename.  reformime tries to choose the default filename
           based on the MIME headers, if possible. If not, the default
           filename will be attachment1.dat (if the -s option is not
           specified, the next filename will be attachment2.dat, and so on).

       -xPREFIX
           Automatic extraction.  reformime automatically extracts one or more
           MIME sections, and saves them to a file. The filename is formed by
           taking PREFIX, and appending the default filename to it. Note that
           there's no space between "-x" and "PREFIX". For example:

               reformime -xfiles-
           This command saves MIME sections as files-attachment1.dat, then
           files-attachment2.dat, etc.  reformime tries to append the filename
           specified in the MIME headers for each section, where possible.
           reformime replaces all suspect characters with the underscore
           character.

       -X prog arg1 arg2 ...
           The -X option must be the last option to reformime.  reformime runs
           an external program prog, and pipes the contents of the MIME
           section to the program.  reformime sets the environment variable
           CONTENT_TYPE to the MIME content type. The environment variable
           FILENAME gets set to the default filename of reformime's liking. If
           the -s option is not specified, the program runs once for every
           MIME section in the message. The external program, prog must
           terminate with a zero exit status in order for reformime to proceed
           to the next MIME section in the message (or the next section
           specified by -s). In any case, if prog terminates with a non-zero
           exit status, reformime terminates with the exit status of 20 plus
           prog's exit status.

           Note
           reformime extracts every MIME section in the message unless the -s
           option is specified. This includes even the text/plain MIME content
           that usually precedes a binary attachment.

   Adding RFC 2045 MIME headers
       The -r option performs the following actions:

       If there is no Mime-Version:, Content-Type:, or
       Content-Transfer-Encoding: header, reformime adds one.

       If the Content-Transfer-Encoding: header contains 8bit or raw, but only
       seven-bit data is found, reformime changes the
       Content-Transfer-Encoding header to 7bit.

       -r7 does the same thing, but also converts 8bit-encoded content that
       contains eight-bit characters to quoted-printable encoding.

       -r8 does the same thing, but also converts quoted-printable-encoded
       content to 8bit, except in some situations.

   Creating multipart/digest MIME digests
       The -m option creates a MIME digest.  reformime reads a list of
       filenames on standard input. Each line read from standard input
       contains the name of a file that is presumed to contain an RFC
       2822-formatted message.  reformime splices all files into a
       multipart/digest MIME section, and writes it to standard output.

   Translating MIME headers
       The following options do not read a message from standard input. These
       options process MIME headers via the command line, and are designed to
       be conveniently used by mail-handling scripts.

       -h "header"
           Decode a MIME-encoded "header" and print the decoded 8-bit content
           on standard output. The decoding gets carried out as if the
           contents occurred in the "Subject" header. Example:

               $ reformime -h '=?iso-8859-1?Q?H=F3la!?='
               HA3la!

       -H "header"
           Like -h except that header is parsed as a list of email addresses,
           like "From" or "To".

       -o "text"
           MIME-encode "text", and print the results on standard output.

       -O "text"
           Like the -o option, except that text is a structured header with
           RFC 2822 addresses.

       -c "charset"
           Use charset as the character set setting, by the -h, -H, -o and -O
           options.

       -u
           This "undocumented" option reads a MIME message on standard input,
           and converts its contents to an UTF-8-encoded character stream,
           which is written to standard output.

           The standard output receives a concatenated amalgam of the headers
           and "text" MIME object data. It is meant to be used as part of a
           generic search function. This option decodes various kinds of
           header MIME encoding, the quoted-printable and base64 transfer
           encodings of "text" MIME objects.
