[daisy] how to enter comments for revisions?

[Bertrand Delacretaz]

Is there a way to add a revision comment when editing stuff in Daisy at 
"cocoon.zones.apache.org/" ?

Use case (fairly obvious ;-) : I just corrected a typo and would like 
to add the comment "I just corrected a typo" to this revision.

Bear with me if the answer is obvious: it's only Monday here...
