"Cue" is a small mail user agent (mail reader/writer).
Features:
- capable of handling Japanese and English (or ASCII) emails (no Latin1)
- S/MIME, and MIME Multipart handling
- it looks just like mh-e or mew, but is much more lightweight. It is not
an elisp program but an independent program that uses curses.
