[bug-mailutils] Usage of folder_ interface?

[Stephen Bylo]

Hi,

I am looking into the mailutils' folder_* interface.  It seems that it
only handles local directories, ie. a collection of mailboxes in a
directory like /var/mail/.

Is it not possible to process a collection of mailboxes no matter if
it's mbox/maildir/mh or imap?
I would expect mailutils to offer an interface so I can do the
following. 

List all mailboxes eg. in
        imap://address@hidden/ or
        mbox:/some_path_to_folder_containing_mailboxes/
        
Subscribe to or create a mailbox eg. create "new" mailbox
        imap://address@hidden/new or
        maildir:/path_to_folder/new

rename, delete mailboxes etc etc.

... but i find that eg. folder_create only accepts a file path string
and not a proper url.

Am i looking in the wrong place?!
I see mbox/folder.c implements "folder_mbox_list()" and 
imap/folder.c "folder_imap_list()".  Is this what I need?

Thanxs for any help or examples.
Steve
