1 Convert mimedecode.py library from global functions to a class.
13 Replace getopt with argparse.
16 Move mimedecode to https://phdru.name/Software/Python/mimedecode/ .
25 Process message/delivery-status and text/rfc822-headers subparts.
28 Never decode subparts of multipart/encrypted and multipart/signed messages but
29 allow processing of headers of the top-level part, ignoring the top-level part
30 with -I, aborting it with -e or saving the part or subparts with --save-*.
33 Convert dates to the current locale and timezone (with an option?)
36 Allow -d and -p accept shell-like patterns and/or regular expressions:
37 -d content-*,-content-*-encoding
40 Add option --save-as='%format' to generate names for --save-* files. Develop
41 a DSL to conditionally use values of headers, parameters and the counter.
