Agent in batch mode for imap

[Julien Cubizolles]

I'm thinking of using the following setup, so that emacs isn't stuck
while gnus checks for new mail.

start gnus in unplugged mode
have a cron job run 

--8<---------------cut here---------------start------------->8---
emacs -batch -l ~/.emacs -l ~/.gnus.el -f gnus-agent-batch >/dev/null 2>&1
--8<---------------cut here---------------end--------------->8---

Will a line like
--8<---------------cut here---------------start------------->8---
(gnus-demon-add-handler 'gnus-group-get-new-news 10 nil)
--8<---------------cut here---------------end--------------->8---
refresh the group buffer ?

I'm not sure about how moving and deleting messages from an imap server
with this setup. These aren't operations you can make while
unplugged and I will certainly have to plug the agent from time to
time. Won't there be a conflict between the moving/copying operations
and the fetch from the agent in batch mode ?

How are you using gnus-agent-batch with imap ?
