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!?='
	       Hola!

       -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.
