where is the documentation about IMAP folders o Shared folders?

[Fabi�n Eduardo Barco]

Hi,

I don't find documentation about IMAP folders o Shared folders neither in
the software documentation nor FAQ
(http://asg.web.cmu.edu/cyrus/imapd/install-FAQ.html) nor Linux-Cyrus-Howto
(http://www.linuxdoc.org/HOWTO/Cyrus-IMAP.html)

Thanks you for any information.

Fabian
