<P>MHonArc is known to run under Unix-based operating systems,
MS-DOS/Windows, WinNT, Win95/98, and OS/2.  If Perl is available for
the system you are using, you can probably run MHonArc.

<P>MHonArc has been coded to support MacPerl, and a couple of
users have reported that MHonArc will run under MacPerl.  I
recommend trying it out, and if you have problems, send a message
to the MHonArc mailing list.

<p>The question is better stated as: <b>"What mail message storage formats
MHonArc support?"</b></p>

<P>MHonArc can convert mail that is stored in UUCP mailbox
format (ie. all messages are in a single file), or in the format used
by the 
<a href="http://www.ics.uci.edu/~mh/">Rand Message Handler</a>
(MH) (messages are contained in separate
files within a directory). MHonArc is known to work with
the following MUAs: <EM>MH/nmh</EM>, <EM>mail</EM>, <EM>Mail</EM>,
<EM>Elm</EM>, <EM>Eudora</EM>, <EM>WinVN</EM>, <EM>Windows
Trumpet</EM>, and <EM>NUPop</EM>.  </P>

<DT><STRONG>NOTE</STRONG> 

<DD><P>To support some MUA's, it may require redefining the
MSGSEP or MHPATTERN resource.  Please consult the documentation
for more information about these resources.</P>

&gt; Hi...
&gt; 
&gt;    Has anyone come up with a relatively clean method of converting 
&gt; majordomo digests to a mailbox format that MHonarc can read?
&gt; 
&gt;    I was looking at it, and from what I can see its just a matter of
&gt; changing the file so that there is a From &lt;&gt; line at the top of each
&gt; message, so that something like:

If you have the procmail package, formail should do it for you.

   formail -ds &lt; digestfile &gt;&gt; newmailbox

It auto-generates the initial 'From ' header.  Unfortunately, it
also leaves the original digest message (probably).  If it's the
first message output, do this:

   formail +1 -ds &lt; digestfile &gt;&gt; newmailbox

This tells formail to skip the first message (the one that came from
list-digest-owner or whatever).

Hi...

	I've searched the archives for some brain dead simple way of bring in old
digests so that MHonarc can use them, and couldn't find anything but some 
references to procmail and -msgsep...nothing which seemed to work "easily"...

	So, here is my contribution...a simple, brain dead script that takes a
Majordomo digest and converts it to a format that can be used by MHonarc...
I don't guarantee it, but if anyone can suggest what is wrong with it, I'd
like to know and try to fix it

	Just run it as: &lt;scriptname&gt; &lt;infile&gt; &gt; &lt;outfile&gt;

Here is a simple script I wrote to process the archives of my Listprocessor 
lists. 

#!/usr/local/bin/perl5
#
# mhonarch.pl - Process all Listprocessor archives using MHonArc
#
# Kevin McCann
#
#### Directory locations:
#
# Listproc, Majordomo, or Listserv top archives dir 
$ARCHDIR = "/usr/server/archives";
#
# MhonArch web archives directory   
$MONDIR = "/u/www/htdocs/listproc/mhonarc";
#
## Let's figure out what lists exist
opendir(DIR,"$ARCHDIR/") || die "Can't open directory";
@dirs = readdir(DIR);
@sorteddirs = sort @dirs;
closedir(DIR);
for (@sorteddirs) {      # processing a list
   $listname = $_;
   opendir(DIR,"$ARCHDIR/$listname") || die "Can't open directory";
   @logs = readdir(DIR);
   @sortedlogs = sort @logs;
   closedir(DIR);
   for (@sortedlogs) {
     if (/log/) {                # processing files with name format 
'logYYMM'
       $log = $_;

       system("/usr/local/bin/mhonarc  -outdir  $MONDIR/$listname/$log  
$ARCHDIR/$listname/$log")

                 # modify the above command line as needed 
     }
   }
  }

}             # end of script


I processed over 100 lists that go back to 1995 with this. It took about 
one hour. There may be more elegant ways to do it, but this was just a 
quick hack to get the job done. If you are using an RCFILE, don't forget to 
include it in the long mhonarc command seen above. Oh, and don't forget to 
change the first line that specifies your Perl location if you need to - 
mine is set to /usr/local/bin/perl5.

Good luck!

<h3><b><a name="ezmlm">Can MHonArc process ezmlm archives?</a></b></h3>
</td></tr></table>

<p>From what I read from the <b>ezmlm(5)</b> manpage, the following example
command will process all messages of list:
</p>
<pre>
    shell&gt; <b>mhonarc <var>/list/archive/</var>[0-9]*</b>
</pre>
<p>Replace "<tt>/list/archive/</tt>" to what is appropriate for your
configuration.
</p>
<p>Basically, each numeric subdirectory in the "<var>archive</var>" directory
follows the same format as MH mail directories.
</p>
<p>If you are using a shell that cannot handle "<tt>[0-9]*</tt>", the following
should work:
</p>
<pre>
    shell&gt; <b>mhonarc `find <var>/list/archive/</var> -type d -name '[0-9]*' -print`</b>
</pre>
<p>Note, make sure to add any additional options to mhonarc as needed
to get the effects you desire.

<h3><b><a name="maildir">Can MHonArc process qmail's maildir style mail folders?</a></b></h3>
</td></tr></table>

<p>For simplicity, let "<var>MAILDIR</var>" represent the pathname
to your qmail mail directory.
</p>
<p>To have mhonarc process <var>MAILDIR</var>,
you pass "<var>MAILDIR</var><tt>/cur</tt>" and/or
"<var>MAILDIR</var><tt>/new</tt>" as the mail folder arguments.
Which subdirectory you choose to use depends on your needs.
</p>
<p>Also, you will need to define the MHPATTERN resource to process
all non-dotfiles.  Example:
</p>
<pre>
    shell&gt; <b>mhonarc -mhpattern '^[^\.]' <var>MAILDIR</var>/cur</b>
</pre>
<p>If all you will ever do is process qmail maildir folders, it may be best
to set the M2H_MHPATTERN environment variable so you do not have
to respecify each time you invoke mhonarc.  Examples:
</p>
<dl>
<dt>csh:
    <dd><b><tt>setenv M2H_MHPATTERN '^[^\.]'</tt></b>
<dt>sh:
    <dd><b><tt>M2H_MHPATTERN='^[^\.]'; export M2H_MHPATTERN</tt></b>

<tr valign=top><td><img src="monicon.png" align="bottom" alt=""></td><td>
<h3><b><a name="netscape">Can MHonArc process Netscape Messenger folders?</a></b></h3>
</td></tr></table>

<p>Yes.  Each Netscape Messenger folder has a corresponding mailbox file
that stores the raw mail messages for the folder.  The location
of the mailbox file will be in your mail directory.  Under Unix, this
is normally <b><tt>$HOME/nsmail</tt></b>.  For Windows, this is
typically
<b><tt>C:\Program Files\Netscape\Users\<var>&lt;username&gt;</var>\Mail</tt></b>.
</p>

<p>For each Netscape folder, there are two files: 
<b><tt><i>&lt;folder-name&gt;</i></tt></b> and 
<b><tt><i>&lt;folder-name&gt;</i>.summary</tt></b> (or
<b><tt><i>&lt;folder-name&gt;</i>.snm</tt></b> under Windows).
The <b><tt>.summary</tt></b> can be ignored with respect to MHonArc.
The other file contains the raw mail messages and can be passed
directly to MHonArc for processing.  For example, to process all the
mail in your Inbox, do something like the following:
</p>
<pre>
    shell&gt; <b>mhonarc $HOME/nsmail/Inbox</b>
</pre>

<p>Note, you may need to compress/compact folders in Netscape before
running MHonArc.  If not, messages you have deleted from a folder may
show up in the archive create by MHonArc.

of the mailbox file will be in your mail directory which is
typically <b><tt>$HOME/evolution/local/<em>folder-name</em></tt></b>.
In the directory is a file called <tt>mbox</tt> which contains
the raw messages that can be passed into MHonArc directly.

The Compuserve "file cabinet" format is too far from the basic SMTP message
format that MHonArc recognizes.

Your friend can find software on Compuserve to read the file cabinet format
and emit ascii text that is closer to SMTP message format that MHonArc can
use.  A search of IBMFF using the keywords "cabinet" and "convert" yielded
several items including these two:

<h3><b><a name="otherformats">What about other mailbox/folder formats?</a></b></h3>

<p>The common technique is to convert the foreign format into
a format recognized by MHonArc: UUCP mailbox or MH mail folders.  The
conversion can also rely on the usage of the MSGSEP and MHPATTERN
resources to make conversion potentially easier.
</p>
<p>A potential source for help is
<a href="http://mango.human.cornell.edu/kens/MoreFAQ.html#Convert"
>&lt;http://mango.human.cornell.edu/kens/MoreFAQ.html#Convert&gt;</a>.  The
URL is part of the Eudora FAQ.  However, Eudora does uses UUCP-style
mailbox format to store its messagse.  Hence, the information
provided from the URL can be applicable to MHonArc.

<p>Yes.  With MHonArc's page layout customizations features,
you can have MHonArc create pages in any language supported
by Web client software.  Plus, messages containing non-English text
is supported during message conversion via the CHARSETCONVERTERS
resource.

<p>Yes.  You can actually create archives that have as many
indexes as you want in as many languages that you want.  Through
the OTHERINDEXES resource can define any number of extra indexes
to create.  For each index, you can redfine the index resources
to use whatever text (English or non-English) you desire.
