    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 this is good because it allows us to
-use 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.

    Here is the solution - mimedecode.py.
 
-   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.

+images decoding base64 to html but leaving images encoded, and ignore

+
