Difference between `quick' and `autorefresh'

[Rob Stewart]

Hi,

I am looking online for offlineimap documentation about two flags,
`quick` and `autorefresh', but cannot find what I am looking for. My
questions are:

1. What is the difference between the two flags?
2. What is the units? Seconds.. minutes?

Take this example:

[Repository Remote]
type = IMAP
remoteuser = me at bar.co.uk
remotehost = localhost
remotepass = foo
autorefresh = 1
quick = 2

What will `quick' do (every 2 minutes?) ? What will `autorefresh' do
(every 1 minute?) ?

Better still, could someone point me to the documentation that makes
this distinction?

Thanks,
