The property Action of an SvnChangedEventArgs is of type SvnChangeAction enum, but I can't find what each enum value means. The possible values are None, Add, Delete, Modify and Replace.
I tested and found that:
I can suppose that None is used when a item that has not changed is listed because of the svnlook arguments.
I can't find the explanation for Modify value. It's the same as Replace? When it occurs?
