Nikolaus Schulz 11103e2de2 mbox locking: combine locking functions into one and swap lock order 
We used to create a dotlock file first and then lock with fcntl; swap that
order, since locking first with fcntl seems to be more common.

This patch also adds general mbox lock/unlock methods, which call the
dotlock and fcntl-lock methods, and moves the retry logic there.

When the dotlock and fcntl methods fail to acquire a lock, they now raise
a custom exception "LockUnavailable", which gets caught in the general
lock() method.  That way, if we succeed to acquire one lock but fail to
acquire the other, we can release our locks at the upper level and retry.

archivemail - archive and compress old mail in your mailbox
-----------------------------------------------------------

OVERVIEW:

archivemail is a tool written in python(1) for archiving and compressing old
email in mailboxes. 

It can move messages older than the specified number of days to a separate
'archive' mbox-format mailbox that is compressed with 'gzip'.

For example, have you been subscribing to the 'linux-kernel' mailing list
for the last 6 years and ended up with an 160-meg mailbox that 'mutt' is
taking a long time to load?  'archivemail' can move all messages that are
older than 6 months to a separate compressed mailbox, and leave you with
just the most recent messages. 

'archivemail' can save a lot of disk space and will significantly reduce
overhead on your mail reader. The number of days before mail is considered
'old' is up to you, but the default is 180 days. You can also archive messages
by an absolute date or only archive unread messages.


REQUIREMENTS:

archivemail requires python version 2.3. It also uses some optional python
modules, but these should be pretty much standard; if you get an ImportError
nonetheless, please report it, thanks. (For contact addresses see below.)

Python is available from http://www.python.org/


INSTALLATION:

If you want to test archivemail:
    cp archivemail archivemail.py
    python test_archivemail.py
    (NOTE: This could take over 90 seconds on slower systems)

To install archivemail, run:
    python setup.py install


USE:

For more detailed information and examples, look at the archivemail man page.

The best way to run archivemail is from cron, giving the '-q' option to
archivemail to make it quiet, only printing messages if something went wrong.
Check out the 'examples' directory for an example shell script to be run from
cron.

The archivemail website is at: http://archivemail.sourceforge.net/
