V0.2 Changes 
============

The variable $friendly now is set to the friendly part of the sender's
email address. For example, if the sender's address is:

	[e-mail] (Martin Streicher)

$friendly would be set to "Martin Streicher"



Keys for the %headers array are all lowercase. That is to say that if a mail
message has headers:

	To: strike
	Cc: george
	From: [e-mail]
	Subject: News

the keys for %header will be "to", "from", "cc", "subject". $header{"subject"}
would be set to "News"



The "Received" headers in a mail message are now saved in an array called
@received. The first element in the array is the first received header;
that last element in the array would show the message being delivered to
your machine. See the Suggestions file for how to use this feature.



If someone from your local machine sends you email, $organization
is set to "local". If the site name (e.g.,"convex" for "pixel.convex.com")
cannot be determined, $organization is set to "unknown". Also, $organization
is much more reliable (I have not found a case yet where $organization
was not set correctly.) 



$organization is always in lower-case.



audit.pl was broken up to make the code more reusable. The utilities
refileto and refilefrom use some of the routines in audit.pl and mh.pl.



Fixed a bug that sometimes added NULL to an empty message body.



mh.pl has new routines to recursively create a directory path, parse your
MH profile and parse MH-like command line options.


New utilities
=============
There are two new utilities: refileto and rfolder and adjunts refilefrom
and rfolders.

refileto is used to refile messages into log folders according to who
you sent the messages to. refilefrom refiles messages you   have received
according to who sent you the message. 

By default all messages are logged into the folder +log. You can change this
by adding the line:

	Logdir:                 log

to your .mh_profile. Also by default, the current folder is processed.
You can change that also. Here are the command line options for 
refileto/refilefrom:

refileto -help
syntax: refileto [msgs] [switches]
   switches are:
   -debug
   -draft
   -file file
   -help
   -link
   -log +folder
   -nolink
   -nopreserve
   -preserve
   -rmmproc program
   -src +folder
   -verbose


A sample usage might be:

refileto -src +outbox -verbose 

-verbose shows you what is being files and where. Use -debug to check what will
happen without actually refiling the mail messages.

Here is a sample output of the command 
"refileto -src +log/outgoing -verbose all":

refile  -file /gmaster/home/strike/Mail/log/outgoing/5 +log/local/holt
refile  -file /gmaster/home/strike/Mail/log/outgoing/7 +log/convex/sowton
refile  -file /gmaster/home/strike/Mail/log/outgoing/9 +log/convex/lutz 
	+log/convex/sowton



The rfolder utility is like folders: it can recursively descend 
a list of folders. However, you can use rfolder to run another MH command
in every folder it finds. For example, let say you want to sort
all of the subfolders in your +log folder.

You could say:

rfolder +log -all -recurse -verbose -exec sortm -textfield subject

-debug will show you what might happen without actually executing the
command.

By the way, -clean can be used to remove empty folders (empty folders
must be completely empty, without any .# or # files from rmm's, etc.)


You can even use refileto/refilefrom and rfolder(s) to build a new 
log directory from all your existing mail. Ala:

rfolder -all -recurse -verbose -exec refilefrom -log +log -src


rfolders implis the -all -recurse flags
