+.archivemailrc support
 
-Goals for next minor release 
--------------------------------------
-* .archivemailrc support
-* When you get a file-not-found in the 6th mailbox of 10, it aborts the whole
-  run. Better to fail gracefully and keep going.
-* Think about the best way to specify the names of archives created with
-  possibly an --archive-name option.
-* Add more tests (see top of test_archivemail.py)
-* We need some better checking to see if we are really looking at a valid
-  mbox-format mailbox.
-* Lock any original .gz files 
-  - is this necessary?
-* Check for symlink attacks for tempfiles (although we don't use /var/tmp)

-Longer Term goals:
-------------------
-* Add an option to not cut threads.
-* Add MMDF mailbox support
-* Add Babyl mailbox support
-* Add option to archive depending on mailbox size threshold 
-  - is this a good idea?
-* Add option to archive depending on number of messages
-  - is this a good idea?
