[rdiff-backup-users] Backing up multiple directories

[Jochem van Leeuwen]

Hello,

I'm new to the list (and actually never post in mailing lists), so 
excuse me if I make a mistake or something.

I've searched the archives for my 'problem', to no avail. The older 
archives don't allow you to search and my search on Google didn't give 
me any good results either.

My question is pretty simple: Can I back up multiple directories using 
rdiff-backup (if so, how?) or do I need to write a shell script and loop 
trough a list of directories?

Thanks,

Jochem
