Uses Python's included mailbox library to convert mail archives from
maildir [http://en.wikipedia.org/wiki/Maildir] to
mbox [http://en.wikipedia.org/wiki/Mbox] format, icluding subfolder.
See http://docs.python.org/library/mailbox.html#mailbox.Mailbox for
full documentation on this library.
---
To run, save as md2mb.py and run:
$ python md2mb.py [maildir_path] [mbox_filename]
[maildir_path] should be the the path to the actual maildir (containing new,
cur, tmp, and the subfolders, which are hidden directories with names like
.subfolde.subsubfolder.subsubsbfolder);
[mbox_filename] will be newly created, as well as a [mbox_filename].sbd the
directory.
