[Evolution] Scripted migration of e-mail from Thunderbird to Evolution

[Sean Carlos <sean carlos gmail com>]

I'm looking for information on how to perform a basic "automated" 
migration of Thunderbird's mbox data to Evolution. 

It appears I can migrate mail in an mbox format into Evolution by coping 
the mbox files, more or less.  See this script for the details 
(http://www.antezeta.com/beagle/copy_thunderbird.sh) . 

However, I would also like to be able to create Evolution's meta files 
without having to manually open evolution and touch each folder.   By 
meta files, I mean:

*.cmeta
*.ev-summary
*.ibex.index
*.ibex.index.data

On the net, I couldn't find migration examples from Thunderbird nor 
scripts for Mozilla mail.  Evolution does have a built-in import routine 
for Netscape mail, but this is not Thunderbird aware - nor am I aware 
how to launch it from the command line.

I am working with version 2.2.3.

Cheers,

Sean Carlos
