Auto-prune Sent -- Version 1.1

This plugin automatically "prunes" your sent folder to keep it from
filling up with a ton of old junk.

Features
========

* Fast and easy - set it up and forget about it
* Safe defaults prevent data-loss after installation


Known Issues
============

* Probably does not work with SquirrelMail 1.2.x
  If you need/want it to, let me know and I'll consider adapting it.

* If a user enters an invalid value on the "Folder Options" page, there
  is no warning, and it says "options successfully saved".  This is a bit
  misleading, since the option was NOT changed.


Installation
============

* Uncompress this archive in the plugins directory of your SquirrelMail
  installation. (You must have done this already to get to this document!)

* If you want to set a default prune time, edit setup.php and set
  $default_prune_threshold to the number of days after which a message in
  the sent folder will be pruned.  0 means no pruning.

* Run conf.pl, and select 8 (plugins).  Select auto_prune_sent, save,
  and you're done.

* If you did not set $default_prune_threshold > 0, each user will need to
  specifically activate pruning.  To do this, they should use the Folder
  Options screen.


Changelog
=========
1.1 - Added auto_prune_sent_version() call. (Returns string)
	- Moved functions into separate files, hopefully to assist performance
1.0 - Initial version (not widely released)
