WWW::Link::Change - convert messages for link changes Not yet implemented Many things can happen to resources at the other end of Links. This class provides a way for the owners of resources to send messages to people who reference those resources. the resource is essentially the same but has been updated in some major unspecified way which a person referencing it might want to examine. the resource no longer exists and no replacement is known or suggested. The resource is now considered outdated and references to it should be changed to something else. This nothing about whether it has been deleted as old resources are often kept for historical reasons. A resourece has been split into parts which are logically separate. Some references to that resource will want to go one new location and some to another.

new ($message) ($link, newstatus, options)
A WWW::Link::Change can be constructed from either a message from another entity or from the information needed for that change.

as_message
This outputs a string which can be sent and used to construct an equivalent WWW::Link::Change in another place. The message is designed so that it could be used by other languages or even a human.
