<para>
Mail users, especially in non-English countries, often find that mail
-messages arrived in different formats, with different content types, in
-different encodings and charsets. Usually it is good because it allows to use
-an appropriate format/encoding/whatever. Sometimes, though, some unification is
-desirable. For example, one may want to put mail messages into an archive,
-make HTML indices, run search indexer, etc. In such situations converting
-messages to text in one character set and skipping some binary attachments is
-much desirable.

This is a program to decode MIME messages. The program expects one input
-file (either on command line or on stdin) which is treated as an RFC822
-message, and decodes to stdout or an output file. If the file is not an RFC822
-message it is just copied to the output one-to-one. If the file is a simple
-RFC822 message it is decoded as one part. If it is a MIME message with multiple
-parts ("attachments") all parts are decoded. Decoding can be controlled by
-command-line options.

- First, Subject and Content-Disposition headers are examined. If any of those
- exists, it is decoded according to RFC2047. Content-Disposition header is
- not decoded - only its "filename" parameter. Encoded header parameters
- violate the RFC, but widely deployed anyway by ignorant coders who never
- even heard about RFCs. Correct parameter encoding specified by RFC2231. This
- program decodes RFC2231-encoded parameters, too.

- The 4 list options (-beit) require more explanation. They allow a user
-to control body decoding with great flexibility. Think about said mail
-archive; for example, its maintainer wants to put there only texts, convert
-Postscript/PDF to text, pass HTML and images as is, and ignore everything
-else. Easy:
